1.	A body is kept on the floor of a train. When the train accelerates forward, the body gains a backward acceleration. Which force is responsible for the backward acceleration?
Answer» Solution :A TRAIN moving with an ACCELERATION forms a noninertial frame of REFERENCE. A pseudo force develops in such a frame. The pseudo force in this instance acts opposite to the direction of acceleration, and it CAUSES a backward acceleration of the BODY kept on the floor.
