Q. If $q$ is the charge per unit area on the surface of a conductor, then the electric field intensity at a point on the surface is
A) $\left( \frac{q}{\varepsilon_{0}} \right)$ normal to surface
B) $\left( \frac{q}{{2\varepsilon}_{0}} \right)$ normal to surface
C) $\left( \frac{q}{\varepsilon_{0}} \right)$ tangential to surface
D) $\left( \frac{q}{{2\varepsilon}_{0}} \right)$ tangential to surface
Explanation
The correct answer is Option A: $\left( \frac{q}{\varepsilon_{0}} \right)$ normal to surface.
