question_answer 36)

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

Answer:

  (a) If the coin falls behind the passenger that means the train is accelerated. When the coin is tossed it has same velocity as that of train but during the time it is in air its velocity becomes less than that of train (because the train is accelerated), so it falls behind the passenger.
