Question

A passenger in a moving train tosses a coin upward which falls behind him. It implies that the motion of the train is:

• A. uniform
• B. accelerated
• C. along the circular tracks
• D. retarded

Answer 1

The correct option is B

accelerated

1. Acceleration is defined as the rate of change of velocity with respect to time.
2. Acceleration is a vector quantity as it has both magnitude and direction.
3. A passenger in a moving train tosses a coin upward which falls behind him. It implies that the motion of the train is accelerated.
4. It happens because, by the time the coin remains in the air, its velocity reduces, and the velocity of the train increases which results in the coin falling behind the passenger.

Hence, option B is correct.
