An insulated conductor initiallly free from charge is charged by repeated contacts with a plate which after each contact is replenished to a charge `Q`. If `q` is the charge on the conductor after first operation prove that the maximum charge which can be given to the conductor in this way is `(Qq)/(Q-q)`
