Question
A conducting rod PQ of length L = 1.0 m is moving with a uniform speed v = 20 m/s in a uniform magnetic field B = 4.0 T directed into the paper. A capacitor of capacity C = 10 μF is connected as shown in figure. Then
Options
A.qA = + 800 μC and qB = - 800 μC
B.qA = - 800 μC and qB = + 800 μC
C.qA = 0 = qB
D.charge stored in the capacitor increases exponentially with time
Solution
qA = + (Blv) C = (4) (1) (20) (10 × 10-6) = 800μC
qB = - qA = - 800μC
qB = - qA = - 800μC
