Q. The electric field near a conducting surface having a uniform surface charge density $\sigma$ is given by
A) $\frac{\sigma}{\varepsilon_{0}}$ and is parallel to the surface
B) $\frac{2\sigma}{\varepsilon_{0}}$ and is parallel to the surface
C) $\frac{\sigma}{\varepsilon_{0}}$ and is normal to the surface
D) $\frac{2\sigma}{\varepsilon_{0}}$ and is normal to the surface
Explanation
(c) Electric field near the conductor surface is given by $\frac{\sigma}{\varepsilon_{0}}$ and it is perpendicular to surface
