Question

A particle is constrained to move on a straight line path. It returns to the starting point after 10 seconds. The total distance covered by the particle during this time is 30 m. Which is a false statement about the motion of the particle?

Answer 1

if the force is applied on object which causes it to move in straight line then there must be an unbalanced force acted on it which changed its direction of motion

Answer 2

C)         Displacement of the particle is



Correct Answer: C

Solution :

            Displacement of the particle will be zero because it comes back to its starting point             

Average speed =Total distance Total time =30m10 sec=3 m/s
