Statement I: A resistance `R` is connected between the two ends of the parallel smooth conducting rails. A conducting rod lies on these fixed horizontal rails and a uniform constant magnetic field `B` exists perpendicular to the plane of the rails as shown in Fig. if the rod is given a velocity `upsilon` and released as shown in Fig. 3.188, it will stop after some time. the total work done by magnetic field negative.

Statement II: If force acts opposite to direction of velocity its work done is negative.

A

The total work done by magnetic field is negative

B

The total work done by magnetic field is positive.

C

The total work done by magnetic field is zero.

D

loss in kinetic energy of conducting rod is equal to heat generate between R.
