Question
A bar magnet M is allowed to fall towards a fixed conducting ring C. If g is the acceleration due to gravity, v is the velocity of the magnet at t = 2s and s is the distance traveled by it in the same time then:-
Options
A.v > 2g
B.v < 4g
C.s > 2g
D.s < 2g
Solution
Induced current in ring will create such a magnetic field which will repel bar magnet.
