Homework Statement
Imagine a universe that consists of nothing but two planets of unequal mass. The large planet has a large negative charge and the smaller planet has a large (but different) positive charge. Suppose that at some time these two planets collide. Will momentum be conserved during the collision? Explain.
The Attempt at a Solution
I Think momentum conserved because there no external force.
