Figure (5-Q3) shows the displacement of a particle going along the X-axis as a function of time. The force acting on the particle is zero in the region(a) AB(b) BC(c) CD(d) DE.

Answer»

The correct answer is (a) (c)

Explanation:

Only in the reason AB and CD the displacement is directly proportional to time, it means that the particle is moving with a uniform velocity. So in this reason force on the particle is zero.
