Two charged objects 1 and 2 are held at a distance r apart. Object 1 has mass m and charge +3q, and object 2 has mass 2m and charge +q. The objects are released from rest. Assume that the only force exerted on either object is the electric force exerted by the other object.

Part B

When the objects are at a distance 4r apart, what is the speed of object 1?

Part C

When the objects are at a distance 4r apart, what is the speed of object 2?

Part D

When the objects are very far apart, what is the speed of object 1?

Part E

When the objects are very far apart, what is the speed of object 2?
