Figure below shows the displacement-time curve of the particles A and B. Which of the following statements is correct?

Answer»

both A and B move with uniform equal speed
A is ACCELERATED and B is retarded
both A and B move with uniform speeds but the speed of A is more than the speed of B
both A and B move with uniform speeds but the speed of B is more than the speed of A.

Solution :Because x - t graph is a STRAIGHT line in EITHER CASE, velocity of both is uniform. As the slope of S-t graph for A is greater, VELCOITY of A is greater than that of B.
