Question

The expression for electric field intensity at a point outside uniformly charged thin place 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

The correct option is A independent of d

The required electric field is given by $\frac{\sigma }{{ϵ}_o}$ for point near plane sheet.

Hence, field is independent of d.

Hence, answer is option-(A).
