Question

A , B , C , D , E , F are conducting plates each of area A and any two consecutive plates separated by a distance d . The net energy stored in the system after the switch is closed is, 3 ε 0 A 2 d V 2, 5 ε 0 A 12 d V 2, ε 0 A 2 d V 2, ε 0 A d V 2

MARKS App · Accepted Answer

C e f f = ε 0 A d since effective field between plates A and E is zero ∴ U = 1 2 C V 2 = ε 0 A 2 d V 2
