A conducting rod of length is moved at constant velocity vo on two parallel conducting smooth fixed rails that are placed in a uniform constant magnetic field B perpendicular to the plane of the rails as shown in figure A resistance R is connected between the two ends of the rail Then which of the following is are correct R www A 8 x B X B The thermal power dissipated in the resistor is equal to rate of work done by external person pulling the rod If applied external force is doubled than a part of external power increases the velocity of rod C Lenz s Law is not satisfied if the rod is accelerated by external force V If resistance R is doubled then power required to maintain the constant velocity vo becomes half
