MCQ

The expression for electric field intensity at a point outside uniformly charged thin plane sheet is ( $d$ is the distance of point from plane sheet)

✓
independent of $d$.
B
directly proportional to $\sqrt{d}$.
C
directly proportional to $d$.
D
directly proportional to $\frac{1}{\sqrt{d}}$.

✓

Answer

Correct option: A.

independent of $d$.

(a) : Electric field intensity outside sheet is $\frac{\sigma}{2 \varepsilon_0}$.
So it is independent of $d$.
