Derive the general potential expression for conducting sphere and charge distribution?
Homework Answers
I have used Gauss's law to find electric field due to to a
conducting sphere and then by integrating, found out the potential.
Then, from the concept of superposition principle, I found out
expressions for potentials for different charge
distributions.
