Two insulating spheres have radii 0.300 cm and 0.500 cm, masses 0.100 kg and 0.700 kg, and uniformly distributed charges of !2.00 +C and 3.00 +C. They are released from rest when their centers are separated by 1.00 m.
(a) How fast will each be moving when they collide? (Suggestion: consider conservation of energy and of linear momentum)
(b) What If? If the spheres were conductors, would the speeds be greater or less than those calculated in part (a)? Explain.
