Description : A man in a train moving with a constant velocity drops a ball on the platform. The path of the ban as seen by an observer standing on the platform is – (1) A straight line (2) A circle (3) A parabola (4) None of these

Last Answer : (3) A parabola Explanation: In the reference frame of the platform the ball has initial horizontal velocity equal to the velocity of the train. The vertical direction is the same observed on the train because both observers agree that gravity is acting on the ball causing an acceleration g.
