  • question_answer
    A boy sitting on the topmost berth in the compartment of a train which is just going to stop on a railway station, drops an apple aiming at the open hand of his brother sitting vertically below his hands at a distance of about 2 meter. The apple will fall                                  [CPMT 1986]            

    A)                         Precisely on 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 in the direction opposite to the direction of motion of the train            

    D)  None of the above

    Correct Answer: B

    Solution :

                                Horizontal velocity of apple will remain same but due to retardation of train, velocity of train and hence velocity of boy w.r.t. ground decreases, so apple falls away from the hand of boy in the direction of motion of the train.
