Charge Q=+ 3.00 μC is distributed uniformly over the volume of an insulating sphere that has radius R = 6.00 cm .What is the potential difference between the center of the sphere and the surface of the sphere?
For an insulating sphere distributed by charge, the potential function at an outside point and at an inside point are different.
The potential at an outside point is given as(x>R)
x is the distance of the point from the center. The above function is for x > R or x = R
The potential at an inside point is given as (x<R)
Therefore, from the question,
Potential at surface is:
The potential at the center is given by:
Therefore, potential difference is:
