​

Answer 1

The answer and explanation are given below.

Explanation:

• Option 2. The train moving forward and gaining speed is the correct answer.
• When the frame of reference has started acceleration compared to a non-accelerating frame, then the pseudo force comes into effect.
• From the frame of reference of the train, a pseudo force on the ball tossed by Ashish must act in a backward direction for it to move behind, which is attainable only when the train is moving forward and gaining speed.
