To solid spheres (perfectly-conducting) have a volumetric mass density ρ. One of the spheres has a radius of R (has a net charge -Q) and the other has a radius of 2R (with a net charge of 2Q). They are released from rest with their centers 6R apart in a vacuum in no gravitational field.

Part 1: At what speeds are the spheres moving when they strike each other?

Part 2: If they rebound elastically and can transfer charge by contact instantaneously, at what speeds are they moving when they return to where they started?
