Question
1)Three conducting spheres of identical radius but made ofdifferent metals copper, silver and gold. One of the spheres(gold) carries excess charge of +Q. If they are all broughtinto contact by a metal rod and then separated, what will be thecharge on all three spheres? 2)A certain charge Q is divided into 2 parts. One is qand the other is Q-q. These two charges are then separated bysome distance r. What must be q in terms of Q such that theelectrostatic repulsive force between the charges is maximum? 3) 3 particls are on the x-axis. Particle 1 of charge q1 is atx= -a and particle 2 of charge q2 is at x=+a. If the net electrostatic force on particle of charge Q isto be zero, what must the ratio of q1/q2 be ifparticle 3 is at x = 0.5a? 1)Three conducting spheres of identical radius but made ofdifferent metals copper, silver and gold.

1)Three conducting spheres of identical radius but made ofdifferent metals copper, silver and gold. One of the spheres(gold) carries excess charge of +Q. If they are all broughtinto contact by a metal rod and then separated,then the charge onall three spheres = Q / 3
2)charge one>
Charge on another = Q – q
