Q. Which of the following is the correct statement of Gauss law for electrostatics in a region of charge distribution in free space?
A) $\oint_{}^{}E.ds = 0$
B) $\oint_{}^{}{E.}ds = \frac{\rho}{\varepsilon_{0}}$
C) $\oint_{}^{}{E.}ds = \rho$
D) $\oint_{}^{}E.ds = \varepsilon_{0}\rho$
Explanation
(b) According to Gauss law of electrostatics in a region of charge distribution in free space.
$\oint_{}^{}{\mathbf{E.ds} = \frac{\rho}{\varepsilon_{0}}}$
