2. Electric Potential and Capacitance
easy
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
Solution
(c) Electric field near the conductor surface is given by $\frac{\sigma }{{{\varepsilon _0}}}$ and it is perpendicular to surface.
