Electric field intensity due to a charged sphere at a point outside the sphere decreases with `"……………….."`.

Options

A. increase in charge on sphere
B. increase in dielectric constant.
C. decrease in the distance of from the centre of sphere.
D. decrease in the square of distance from the centre of sphere.

Answer

b

Explanation

Increase in dielectric constant
Electric field intensity at a point outside a charged conducting sphere is given as
`E = 1/(4piepsi).(q)/(r^(2))`
