Figure shows a conducting rod of negligible resistance that can side on smooth U shaped rail make of wire of resistance 1 22 m Position of the conducting rod at t 0 is shown A time dependent magnetic field B 2t Tesla is switched on at t 0 After the magnetic field is switched on the conducting rod is moved to the left perpendicular to the rails at constant speed 5 cm s by some external agent 20 cm 8 Conducting Rod l 40 cm 1 The current in the loop at t 0 due to induced emf is 0 16 A clockwise 2 At t 2s induced emf has magnitude 0 08 V 3 The magnitude of the force required to move the conducting rod at constant speed 5 cm s at t 2s is equal to 0 08 N 4 The magnitude of the force required to move the conducting rod at constant speed 5 cm s at t 2s is equal to 0 16 N
