Three identical conducting plates are arranged as shown in figure and they are given charges as indicated. When switch S is closed , The amount of charge flown through the switch is@Kajal
q3=0 (Because plate A is grounded) and charge on plate C is 70 micro C So q2=-70 micro C and On B -q1+q2= 30 micro C SO q1=100 micro C SO the amount of charge flown through the switch Let say Q So Q+q1= 20 micro C So Q= 120 micro C
