Question

The inward and outward electric flux for a closed surface in units of $Nm2/C$ are respectively $8\times {10}^3$ and $4\times {10}^3$. Then the total charge inside the surface in S .I . units is (where ${ϵ}_0=$ permittivity in free space)

• A. $4\times {10}^3$
• B. $-4\times {10}^3$
• C. $\frac{(-4\times {10}^3)}{{ϵ}_0}$
• D. $-4\times {10}^3{\in }_0$
