B A conducting square loop of side a is kept on a sufficiently rough horizontal surface and connected to a charged capacitor as shown in the figure The arms AB BE FC CD and DA are rigid but connecting wires EG FH can behave as strings so that the whole loop can rotate about BC The mass of each arm is m and the gap between points E and F can be neglected A uniform 5km g is the amount magnetic field is present in the x direction Upon closing the switch 3B a charge flown in circuit so as to rotate the loop by 90 about BC then find the value of k negle the resistance of wires X E C F G H q g
