Text Solution

Verified by Experts

Inertia is the measure of the mass of the body . The greater is the mass of the body, the greater is its inertia and vice-versa.
(a) Mass of a stone is more than the mass of a rubber ball for the same size. Hence, inertia of the stone is greater than that of a rubber ball.
(b) Mass of a train is more than the mass of a bicycle. Hence inertia of the train is greater than that of bicycle.
( c) Mass of a five rupee coin is more than that of a one-rupee coin. Hence, inertia of the five rupee coin is greater than that of the one rupee coin.
