The ratio of the side of the two square loop ABCD and PQRS is 1 : 2. The ratio of the resistance of the arm AB to arm PQ is 2 : 1 and the resistance of the other arms is negligible. Both the loops are placed perpendicular in the same magnetic field of intensity B. Find the ratio of the heat dissipated in the loop ABCD to the loop PQRS when the arms AB and PQ are moved towards their opposite arm with same speed.
