(b) Two metal spheres, each of mass 1 gm and radius 0.5 cm are placed on a smooth, horizontal, insulated plate such that their centres are 15 cm apart. One is charged to a potential 500 volt and the other to 1000 volt. What is the velocity of each sphere when they drift away to a distance of 30 cm. between their centres?

On the second I would start with total energy and set it equal to total energy (PE+KE) at 30cm.
