Question

The inward and outward electric flux for a closed surface in units of 2 N-m² /C are respectively $8 cross times 10 cubed text and end text 4 cross times 10 cubed$ Then the total charge inside the surface is [where $epsilon subscript 0 equals$ permittivity constant]

$4 \times 10^{3} C$
$- 4 \times 10^{3} C$
$\frac{(- 4 \times 10^{3})}{ε} C$
$- 4 \times 10^{3} ε_{0} C$

The correct answer is: $negative 4 cross times 10 cubed epsilon subscript 0 straight C$
