The graph between displacement and time in a motion along straight line is depicted below. Which interval indicates that no force is acting on the particle?

A

RS

B

QR

C

PQ

D

OP

Text Solution

Verified by Experts

The correct Answer is:
C
PQ is a horizontal line parallel to time axis. So, velocity is zero, hence acceleration and therefore force is zero.
