Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

A body having zero velocity will not necessarily have zero acceleration.For example : When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero (g=9.8m/s2).Even at the highest point it experiences the force of gravity acting downward . option A option b cannot be correct because even at zero velocity, the body will still have gravitational force acting on it. Thus it will have some acceleration
can option b also be the correct answer?
