The density of the charge inside of the sphere is given-
The electric potential on the outer layer of the sphere is phi=0
The radius of the sphere is 58.4m
r-is the distance from the center of the sphere
What is the electric potential when r=15.4m?
The Attempt at a Solution
Basically, what I tried to do the to do the field equation and integrate it between 58.4 and 15.4.
That didnt work so im clueless to what I need to do.
