    A boy, sitting on the topmost birth in the compartment of a train which is just going to stop on the railway station, drops an apple aiming at the open hand of his brother situated vertically below his own hand at a distance of 2m. The apple will fall

    A) in the hand of his brother

    B) slightly away from the hand of his brother in the direction of motion of the train

    C) slightly away from the hand of his brother opposite to the direction of motion of the train

    D) None of the above

    Correct Answer: B

    Solution :

    [b] The apple will fall slightly away from the hand of his brother in the direction of motion of the train due to inertia of motion. When train is just going to stop, the boy and his brother slows down with train but the apple which is in free fall continue to move with the same speed and therefore, falls slightly away from the hand in the direction of motion of the train.
