Chapter 21 | Problem 90 | Physics for Scientists and Engineers 4e (Giancoli) Solution

TWO small, identical conducting spheres A and B are a distance R
apart; each carries the same charge Q. (a) What is the force
sphere B exerts on sphere A? (b) An identical sphere with zero
charge, sphere C, makes contact with sphere B and is then moved
very far away. What is the net force now acting on sphere A?
(c) Sphere C is brought back and now makes contact with
sphere A and is then moved far away. What is the force on
sphere A in this third case?
