金声玉亮2.0 The electric flux through a closed surface is related to the net charge enclosed by the surface by Gauss's Law, which states that the electric flux \(\Phi_E\) through a closed surface is equal to the net charge \(q_{enc}\) enclosed by the surface divided by the permittivity of free space \(\epsilon_0\).

\[ \Phi_E = \frac{q_{enc}}{\epsilon_0} \]

Rearranging this equation to solve for the net charge enclosed, we get:

\[ q_{enc} = \Phi_E \cdot \epsilon_0 \]

Given that the electric flux \(\Phi_E = 4.0 \times 10^4 N \cdot m^2/C\) and the permittivity of free space \(\epsilon_0 = 8.85 \times 10^{-12} C^2/(N \cdot m^2)\), we can calculate the net charge enclosed:

\[ q_{enc} = (4.0 \times 10^4 N \cdot m^2/C) \cdot (8.85 \times 10^{-12} C^2/(N \cdot m^2)) \]

\[ q_{enc} = 3.54 \times 10^{-7} C \]

Therefore, the net charge enclosed by the surface is \(3.54 \times 10^{-7} C\).

The net charge enclosed by the spherical surface can be determined using **Gauss's Law**, which states:

\[
\Phi = \frac{Q_{\text{enclosed}}}{\varepsilon_0}
\]

Rearranging to solve for \( Q_{\text{enclosed}} \):

\[
Q_{\text{enclosed}} = \Phi \cdot \varepsilon_0
\]

**Given**:
- Electric flux (\( \Phi \)) = \( 4.0 \times 10^4 \, \mathrm{N \cdot m^2/C} \)
- Permittivity of free space (\( \varepsilon_0 \)) = \( 8.85 \times 10^{-12} \, \mathrm{C^2/(N \cdot m^2)} \)

**Calculation**:
\[
Q_{\text{enclosed}} = (4.0 \times 10^4) \cdot (8.85 \times 10^{-12}) = 3.54 \times 10^{-7} \, \mathrm{C}
\]

**Rounding** to **2 significant figures** (since \( 4.0 \times 10^4 \) has 2 sig figs):

\[
Q_{\text{enclosed}} = 3.5 \times 10^{-7} \, \mathrm{C}
\]

**Final Answer**:
\[
\boxed{3.5 \times 10^{-7} \, \mathrm{C}}
\]

gpto1 To find the net charge enclosed by the spherical surface, we can use Gauss's Law, which relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's Law is given by:

\[
\Phi_E = \frac{Q_{\text{enc}}}{\varepsilon_0}
\]

Where:
- \(\Phi_E\) is the electric flux through the surface.
- \(Q_{\text{enc}}\) is the net charge enclosed.
- \(\varepsilon_0\) is the vacuum permittivity (\(\varepsilon_0 = 8.85 \times 10^{-12} \,\text{C}^2/\text{N}\cdot\text{m}^2\)).

We are given the electric flux:

\[
\Phi_E = 4.0 \times 10^4 \,\text{N}\cdot\text{m}^2/\text{C}
\]

Rearranging Gauss's Law to solve for \(Q_{\text{enc}}\):

\[
Q_{\text{enc}} = \varepsilon_0 \Phi_E
\]

Substitute the known values:

\[
Q_{\text{enc}} = (8.85 \times 10^{-12} \,\text{C}^2/\text{N}\cdot\text{m}^2) \times (4.0 \times 10^4 \,\text{N}\cdot\text{m}^2/\text{C})
\]

Compute the product:

1. Multiply the numerical coefficients:

\[
8.85 \times 4.0 = 35.4
\]

2. Combine the powers of ten:

\[
10^{-12} \times 10^4 = 10^{-8}
\]

Now, multiply these together:

\[
Q_{\text{enc}} = 35.4 \times 10^{-8} \,\text{C}
\]

To express this in standard scientific notation, adjust the coefficient to be between 1 and 10:

\[
35.4 \times 10^{-8} \,\text{C} = 3.54 \times 10^{-7} \,\text{C}
\]

- \(\epsilon_0\) is the permittivity of free space, which is approximately \(8.854 \times 10^{-12} \, \text{C}^2/\text{N} \cdot \text{m}^2\).

Given:
\[ \Phi_E = 4.0 \times 10^4 \, \text{N} \cdot \text{m}^2/\text{C} \]

We need to find \(Q_{\text{enc}}\).

Rearranging Gauss's Law to solve for \(Q_{\text{enc}}\):

\[ Q_{\text{enc}} = \Phi_E \cdot \epsilon_0 \]

Substitute the given value of \(\Phi_E\) and the known value of \(\epsilon_0\):

\[ Q_{\text{enc}} = (4.0 \times 10^4 \, \text{N} \cdot \text{m}^2/\text{C}) \times (8.854 \times 10^{-12} \, \text{C}^2/\text{N} \cdot \text{m}^2) \]

Now, perform the multiplication:

\[ Q_{\text{enc}} = 4.0 \times 8.854 \times 10^4 \times 10^{-12} \, \text{C} \]
\[ Q_{\text{enc}} = 35.416 \times 10^{-8} \, \text{C} \]
\[ Q_{\text{enc}} = 3.5416 \times 10^{-7} \, \text{C} \]

Therefore, the net charge enclosed by the spherical surface is:

\[ Q_{\text{enc}} \approx 3.54 \times 10^{-7} \, \text{C} \]

This is the net charge enclosed by the surface.

To find the net charge enclosed by the surface, we can use Gauss's law, which states that the electric flux through a closed surface is proportional to the net charge enclosed by the surface.

Mathematically, Gauss's law is expressed as:

Φ = Q / ε₀

where Φ is the electric flux, Q is the net charge enclosed by the surface, and ε₀ is the electric constant (also known as the permittivity of free space).

Rearranging the equation to solve for Q, we get:

Q = Φ × ε₀

Plugging in the given value of the electric flux (4.0 × 10^4 N · m^2/C) and the value of ε₀ (approximately 8.85 × 10^-12 C^2/N · m^2), we get:

Q = (4.0 × 10^4 N · m^2/C) × (8.85 × 10^-12 C^2/N · m^2)
= 3.54 × 10^-7 C

Therefore, the net charge enclosed by the surface is approximately 3.54 × 10^-7 C.

To find the net charge enclosed by the surface, we can use the formula for electric flux:

Φ = Q / ε₀

where Φ is the electric flux, Q is the net charge enclosed by the surface, and ε₀ is the electric constant (also known as the permittivity of free space).

Rearranging the formula to solve for Q, we get:

Q = Φ \* ε₀

The electric constant ε₀ is approximately 8.85 x 10^(-12) C^2/Nm^2.

Plugging in the given value of electric flux Φ = 4.0 x 10^4 Nm^2/C, we get:

Q = (4.0 x 10^4 Nm^2/C) \* (8.85 x 10^(-12) C^2/Nm^2)

Q = 3.54 x 10^(-7) C

Therefore, the net charge enclosed by the surface is approximately 3.54 x 10^(-7) C.

DeepSeek-Coder-V2 To solve the problem of finding the net charge enclosed by a spherical surface given the electric flux through it, we can use Gauss's Law. Gauss's Law states that the electric flux (Φ) through a closed surface is equal to the net charge (Q) enclosed by that surface divided by the permittivity of free space (ε₀). Mathematically, this is expressed as:

Φ = Q / ε₀

Given:
- Electric flux, Φ = 4.0 × 10^4 N·m²/C
- Permittivity of free space, ε₀ = 8.85 × 10^-12 C²/N·m²

We need to find the net charge (Q) enclosed by the surface. Rearranging the formula to solve for Q, we get:

Q = Φ × ε₀

Now, substitute the given values into the equation:

Q = (4.0 × 10^4 N·m²/C) × (8.85 × 10^-12 C²/N·m²)

Perform the multiplication:

Q = 4.0 × 10^4 × 8.85 × 10^-12 C
Q = 35.4 × 10^-8 C
Q = 3.54 × 10^-7 C

Therefore, the net charge enclosed by the spherical surface is:

Q = 3.54 × 10^-7 C

So, the final answer is:

Q = 3.54 × 10^-7 C

baichuan4 To find the net charge enclosed by the spherical surface, we can use Gauss's law for electric flux, which states that the electric flux through a closed surface is proportional to the net charge enclosed by the surface. The formula for Gauss's law is:

$$\Phi_E = \frac{Q_{enc}}{\epsilon_0}$$

where:
- $\Phi_E$ is the electric flux through the surface (in $N \cdot m^2/C$).
- $Q_{enc}$ is the net charge enclosed by the surface (in coulombs, C).
- $\epsilon_0$ is the vacuum permittivity constant, which has a value of approximately $8.854 \times 10^{-12} C^2/N \cdot m^2$.

Given the electric flux through the spherical surface is $4.0 \times 10^4 N \cdot m^2/C$, we can rearrange the formula to solve for $Q_{enc}$:

$$Q_{enc} = \Phi_E \cdot \epsilon_0$$

Substituting the values:

$$Q_{enc} = 4.0 \times 10^4 N \cdot m^2/C \cdot 8.854 \times 10^{-12} C^2/N \cdot m^2$$

$$Q_{enc} = 3.5416 \times 10^{-7} C$$

Therefore, the net charge enclosed by the spherical surface is approximately $3.5416 \times 10^{-7} C$.

doubao The electric flux through a closed surface is given by the equation Φ = Q / epsilon_0, where Phi is the electric flux, Q is the net charge enclosed, and epsilon_0 is the permittivity of free space. The value of epsilon_0 is 8.854 x 10^-12 C^2 / (N m^2).

Rearranging the equation to solve for Q gives Q = Phi * epsilon_0.

Substituting the given values, Q = (4.0 x 10^4 N m^2 / C) * (8.854 x 10^-12 C^2 / (N m^2)) = 3.5416 x 10^-7 C.

So the net charge enclosed by the spherical surface is 3.5416 x 10^-7 C.

$$ \Phi_E = \oint_S \vec{E} \cdot d\vec{A} = \frac{Q_{\text{enc}}}{\varepsilon_0} $$

where $\vec{E}$ is the electric field, $d\vec{A}$ is the differential area vector on the surface $S$, and $\varepsilon_0$ is the vacuum permittivity (also known as the electric constant), with a value of approximately $8.854 \times 10^{-12} C^2/(N \cdot m^2)$.

Given the electric flux $\Phi_E = 4.0 \times 10^4 N \cdot m^2/C$, we can solve for the net charge $Q_{\text{enc}}$ as follows:

$$ Q_{\text{enc}} = \Phi_E \cdot \varepsilon_0 $$

Plugging in the values:

$$ Q_{\text{enc}} = 4.0 \times 10^4 N \cdot m^2/C \cdot 8.854 \times 10^{-12} C^2/(N \cdot m^2) $$

$$ Q_{\text{enc}} = 4.0 \times 8.854 \times 10^4 \times 10^{-12} C $$

$$ Q_{\text{enc}} = 35.416 \times 10^{-8} C $$

$$ Q_{\text{enc}} = 3.5416 \times 10^{-7} C $$

Therefore, the net charge enclosed by the spherical surface is $3.5416 \times 10^{-7}$ Coulombs.
