Q96 / 160 · JIPMER 2014 · Physics

Electric field at point 20 cm away from the centre of dielectric sphere is $100 \mathrm{~V} / \mathrm{m}$, radius of sphere is 10 cm , then the value of electric field at a distance 3 cm from the centre is

A
$100 \mathrm{~V} / \mathrm{m}$
B
$125 \mathrm{~V} / \mathrm{m}$
C
$120 \mathrm{~V} / \mathrm{m}$
Correct answer
D
$0$

Solution

Inside a dielectric sphere, electric field is zero.

Hence, the correct answer is option: 'D'.
