Consider the situation shown in the figure. The wire PQ has a negligible resistance and is made to slide on the three rails with a constant speed of 
. Find the current in the 
resistor, when the switch S is thrown to middle rail.
Text Solution
Verified by ExpertsThe correct answer is:
A
Induced emf in wire PQ will be along 2 cm length because p.d. across middle rail and rail below the middle rail is zero.
I
