Physics - Electrostatics Question with Solution | TestHub

Surface charge density$=\sigma$

Inside the surface, the electric field is zero.

$\Rightarrow E_{\mathrm{i}\mathrm{n}\mathrm{s}\mathrm{i}\mathrm{d}\mathrm{e}}=0$

$\because V_{\mathrm{i}\mathrm{n}\mathrm{s}\mathrm{i}\mathrm{d}\mathrm{e}}=V_{\mathrm{s}\mathrm{u}\mathrm{r}\mathrm{f}\mathrm{a}\mathrm{c}\mathrm{e}}$

The potential inside the surface of charged sphere is constant

$\therefore E=0, V=$constant.
