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

Options

A. Displacement of the particle is zero
B. Average speed of the particle is 3 m/s
C. Displacement of the particle is 30 m
D. Both (a) and (b)

Answer

C

Explanation

Displacement of the particle will be zero because it comes back to its starting point
`v_(avg) = 30/10 = 3m//s`
