Ganesh is a champion in cricket in his school. When he is in the ground (for practice) and he used to whirl his bat in different style. His coach was Mr. Gunalan. The coach asked Ganesh to hold the bat at its handle and roatate fastly. But Ganesh could not do as his coach said, Ganesh developed pain in his hands. Then his coach told him to rotate the bat by holding it at its mid point. When Ganesh rotated at this position, he was able to rotate the bat faster. Ganesh was surprised and asked his coach how. (i) What was coach's explanation to Ganesh ? (ii) What is Radius of Gyration ? Give an example. (iii) How moment of Inertia is related with Angular velocity ?

Shown a circular coil of N turns and radius a, connected to a battery of emf epsilon through a rheostat. The rheostat has a total length L and resistance R. The resistance of the coil is r. A small circular loop of radius a' and resistance r' is placed coaxially with the coil. The centre of the loop is at a distance x from the centre of hte coil. In the beginning, the sliding contact of the rehostat is at the left end and then on wards it is moved towards right at a constant speed v. Find the emf induced int he small circular loop at the instant (a) the contact begins to slide and (b) it has slid thrugh half the length of the rheostat.
