The inward and outward electric flux for a closed surface in units of $\mathrm{N} - \mathrm{m}^2 / \mathrm{C}$ are respectively $8 \times 10^{3}$ and $4 \times 10^{3}$ . Then the total charge inside the surface is [where \varepsilon_0= permittivity constant]
Text Solution
Verified by ExpertsThe correct answer is:
D
By Gauss’s law $\phi = \frac{1}{\varepsilon_0}$ (Q enclosed )
⇒ ⇒ $Q_{enclosed} = \phi \varepsilon_0 = \left(-8 \times 10^3 + 4 \times 10^3 \right) \varepsilon_0$
$= -4 \times 10^{3} \epsilon_{0}$ Coulomb.
