__________ of a two article system depends only on the separation between the two particles. The most appropriate choice for the blank space in the above sentence is

Answer carefully, with reasons : If the potential energy of two billard balls depends only on the separation distance between their centres, is the collision elastic or inelastic? (Note, we are talking here of potential energy corresponding to the force during collision, not gravitational potential energy).

Two charged particle A and B repel each other by a force k/r^2 where is a constant and r is th separation between them. The particle A is clamped to a fixed point in the lab and the particle B which has a mass m, is released from rest with asn initial separartion r_0 form A. Find the change in the potential energyof hte wo particle system as the separation increases to a large value. What will be the speed o the particle b in this situation?
