Question

A passenger in a moving train tosses a coin which falls behind him. This shows that the motion of train is :
(a) accelerated
(b) uniform
(c) retarded
(d) along circular track

Answer 1

If the coin falls behind the passenger that means the train is accelerated. When the coin is tossed it has the same horizontal velocity as that of the train but during the time it is in the air its velocity becomes less than that of the train (because the train is accelerated), so it falls behind the passenger. The coin falls behind because the train is in an accelerated motion and no force is acting on the coin to speed up along with the train.

Hence the correct option is (a) accelerated.
