Question

Three identical large metal plates of area A are small at distances d and 2d from each other. Top metal plate is uncharged, while the other metal plates have charges +Q and −Q. Top and bottom metal plates are connected by switch S through a resistor of unknown resistance. What energy (in mJ) is dissipated in the resistor when switch is closed? (given: d ϵ 0 ​ A ​ =6 μF, Q=60 μC)
