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

A

Displacement of the particle is zero

B

Average speed of the particle is `3 ms^(-1)`

C

Displacement of the particle 30 m

D

Both (a) and (b)

Text Solution

Verified by Experts

The correct Answer is:
D
Displacement of the particle will be zero because it comes back to its starting point.
Average speed `=("Total distance")/("Total time")=(30 m)/(10 s)=3 ms^(-1)`
