Question

Electric intensity due to a charged sphere at a point outside the sphere decreases with...................

Options

• increase in charge on sphere.

• increase in dielectric constant.

• decrease in the distance from the centre of sphere.

• decrease in square of distance from the centre of sphere.

Answer 1

increase in dielectric constant

Electric feild intensity at a point outside a charged conducting sphere is given as

`E=1/(4pi).q/r^2`
