As shown in diagram initial charge on capacitor is zreo . Now switch `S_(1)` is closed & it remains closed for a long time but `S_(2)` remains open . Now switch `S_(1)` is opened & switch `S_(2)` is closed at t=0, then after closing the switch `S_(2)` :

Options

A. Maximum current passing through inductor will be `(epsilon)
sqrt((C)/(2L))`.
B. Maximum magnitude of rate of change of current through inductor will be `(epsilon)/(L)`.
C. Maximum charge on capacitor `C_(2)` will be `epsilonC`.
D. Maximum charge on capacitor `C_(2)` will be `(epsilonC)/(2)`.

Answer

A, B, C
