Compute all parts of following problem given below:
Problem: A sphere of radius r has a potential of 5cos3Θ - 3cosΘ+3 on its surface.
Part A: Find the complete solution for the potential both inside and outside the sphere?
Part B: Determine the charge density on the surface?
Part C: Find the total charge on the surface?
I want help to find the complete solution for the potential both inside and outside the sphere.
