21.Two particles start from rest simultaneously and are equally accelerated. Throughout the motion, the relative velocity of one w.r.t. other is:

zero

non-zero and directed parallel to acceleration

non-zero and directed opposite to acceleration

directed perpendicular to the acceleration

22.A train is moving eastwards with a velocity of 10 m/s. On a parallel track another train passes with a velocity 15 m/s eastwards. To the passengers in the second train, the first train will appear to be moving with a velocity:
