Statement I: A resistance R is connected...

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

(a) Statement I is True, Staatement II is True, Statement II is correct expaination for Statement I.

B

(b) Statement I is True, Staatement II is True, Statement II is NOT a correct expaination for Statement I.

C

( c) statement I is True, Satement II is false.

D

( d) statement I is False, Satement II is True.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Magnetic field cannot do work, hence statement `1` is false.
