Question

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)

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

Answer 1

Answer: (A)

independent of $d$

Answer 2

We know that, the electric field intensity outside the sheet is given by $E_{\text {outside }}=\frac{\sigma}{2 \varepsilon_{0}}$ Therefore, the electric field intensity is independent of $d$.
