Viyaan wants to check the constancy of the acceleration due to gravity in his garden, for which he collects some objects such as a piece of cloth, an iron ball, an apple and drops them all at a time from the same height. He finds that the objects do not land at the same time. Does it mean that the acceleration due to gravity on the Earth is not constant? Give reasons.
