Question

If a coin is tossed by a boy in a moving train and it falls behind him, then the motion of the train is

• A. Uniform
• B. Accelerated
• C. Retarded
• D. Along a circular track

Answer 1

The correct option is B Accelerated

If the train was moving with uniform velocity, then the coil would have fallen at the same place from where it was tossed up.

When the train is accelerating it changes its speed (increases),on the other hand the coin still moves with the same speed as before .So when the coin is tossed, by the time the coin reaches back, the train would have moved ahead and so the coin will fall behind the spot from where it was tossed.
