A solid sphere is charged uniformly throughout its volume with a charge Q. Ratio of electrostatic potential at the centre of the sphere to that of at the surface will be
The answer of this question will be 3/2.
The formula for electrostatic potential at the centre of a solid sphere is 3/2* KQ/R
Similarly the formula for electrostatic potential at the surface of the solid sphere is KQ/R.
If we take ratio of these two, we will get our required answer asked in this question.
