Displacement-time graph of a moving body is shown in the figure. How much force is acting on the body?

Answer:

From the graph, it is clear that the body is moving with uniform velocity i.e., velocity is constant. Hence, acceleration of the body ‘a’ is zero. \[{{v}_{B}}=?\]force acting on the body = F \[=m\times a=m\times 0=0\] Therefore, force acting on the body is zero.
