Question

5 2 A conducting circular loop of radius a and resistance per unit length R is moving with a constant velocity vo parallel to an infinite conducting wire carrying current io a conducting rod of length 2a is approaching the centre of the loop with a constant velocity v 2 along the direction of the current At the instant t 0 the rod comes in contact with the loop at A and starts sliding on the loop with the constant velocity Neglecting the resistance of the rod and any self inductance in the circuit find the following when the rod slides on the loop a The current through the rod when it is at a distance of a 2 from the point A of the loop b Force required to maintain the velocity of the rod at that instant 10 ns a i 9vololo 16aRn a 3 P In 3 b 10 a 10 2 Figure 5 330 Holo Vo 32aRT A 40 In 3 A 5 11 V C J
