Question
Statement-1 : 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 the figure. If the rod is given a velocity v and released as shown in figure, it will stop after some time. The total work done by magnetic field is negative.
Statement-2 : If force acts opposite to direction of velocity its work done is negative.
- Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
- Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1
- Statement-1 is True, Statement-2 is False
- Statement-1 is False, Statement-2 is True
The correct answer is: Statement-1 is False, Statement-2 is True
Magnetic field cannot do work, hence statement-1 is false

A circuit consisting of a constant e.m.f. 'E', a self-induction 'L' and a resistance 'R' is closed at t = 0. The relation between the current I in the circuit and time t is as shown by curve 'a' in the figure. When one or more of parameters E, R & L are changed, the curve 'b' is obtained. The steady state current is same in both the cases. Then it is possible that
