Thread: potential

Find the potential inside and outside a uniformly charge sphere of radius and whose total charge is . Use infinity as your reference point.

So . What is the electric field inside the sphere?

Then outside the sphere . Then .

For inside the sphere how would you compute the potential?

Read Example 4.1: Electric field of a uniformly charged sphere and http://physics.bu.edu/~duffy/semeste...l_spheres.html.
