Question

How to find electric potential in a sphere having spheres within it?

Answer 1

To find Potential due to a non conducting sphere ( where the charge will always be distributed inside the volume of sphere) , take a sphere with total charge inside it be 'Q' and the volumetric charge density be 'ρ'. Let R be the radius of the sphere.We need to calculate potential due to a conducting shell at point ‘P’.

Charged Sphere

Total Charge = Q

Volumetric Charge density = ρ

We know the relation between volumetric charge density (ρ) and total charge within the volume (Q) :

Q =

4πR3
