A constant force `F` is being applied on a rod of length `t` kept at rest on two parallel conducting rails connected at ends by resistance `R` in uniform magnetic field `B` as shown.

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 resistane R is doubled then power required to maintain the constant velocity `v_(0)` becomes half.
