How fast will each be moving when they collide?

+1 vote

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 2.50 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? (Hint: Consider conservation of energy and of linear momentum.)
m/s (lighter sphere)
m/s (heavier sphere)
(b) If the spheres were conductors, would the speeds be greater or less than those calculated in part (a)? (Note: Assume a reference level of potential V = 0 at r = infinity.)
