A uniform spherical volume distribution of charge has radius R and total charge Q. A point charge q is released from rest at point b, which is a distance 3R from the center of the distribution. When the point charge reaches a, which of the following is true regarding the total energy E?

1.Ea = Eb
2.Ea = 2Eb/3
3.Ea = 3Eb/2
4.Ea = 9Eb/4
5.Ea = Eb
6.Ea = 2Eb/3
7.Ea = 3Eb/2
8.Ea = 9Eb/4
