Question

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

Answer 1

Answer: (C)

$\frac{\sigma}{\varepsilon_{0}}$ and is normal to the surface

Answer 2

Electric field near the conductor surface is given by $\frac{\sigma}{\varepsilon_{0}}$ and it is perpendicular to surface.
