The potential at the surface of a sphere with, charge Q, radius r is V(r):
33
Charge density rho is related to the charge Q and radius r by:
34
The work done dW in adding a shell of thickness dr, charge dq is dW:
35
Total work done in building up a sphere of Radius R is:
- also got me a_c??
- Core exercises had R not R_0 and Q not e. This equation was taken from a_c = … which was the next question.
