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)

Options

• independent of d

• directly proportional to `sqrt"d"`

• directly proportional to d

• directly proportional to `1/sqrt"d"`

Answer 1

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

Explanation:

Electric field intensity at a point outside a uniformly charged thin plane sheet = `sigma/(2epsilon_0)`

So it is independent of d.
