1. The problem statement, all variables and given/known data Two insulating spheres have radii 0.300 cm and 0.500 cm, masses 0.200 kg and 0.700 kg, and uniformly distributed charges of -2.00 µC and 3.00 µC. They are released from rest when their centers are separated by 1.00 m. (a) How fast will each be moving when they collide? 2. Relevant equations 3. The attempt at a solution I know i need to use the conservation of energy for the potential and kinetic forces, but I cannot figure out how to appropriately set up the equation in order to do so.
