An electron starts from rest 2.82 cm from the center of a uniformly charged sphere of radius 2.17 cm. If the sphere carries a total charge of 1.11×10-9 C, how fast will the electron be moving when it reaches the surface of the sphere?
This is an exam question that I got wrong and I am trying to figure out how to do it.
So it has something to do with figuring out the potential difference between the eletron's initial position and the surface of the sphere. But how do you do that? Then I know I can use the kinetic energy of the electron to find the velocity
