A conducting rod of length is moved at constant velocity `v_(0)` on two parallel, conducting, smooth, fixed rails, that are placed in a uniform constant magnetic field B perpendicular to the plane for the rails as shown in Fig. A resistance R is connected between the two ends of the rails.
Then which of the following is/are correct:

A

The thermal power dissipated in the resistor is equal to rate of work done by external person pulling the rod.

B

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

D

If resistance `R` is doubled than power required to maintain the constant velocity `v_(0)` becomes half.
