Question

17. The body is stationary whena) Displacement time graph is parallel to time axis b) displacement time graph is a

straight line but not parallel to time axis c) displacement time graph is a straight line

b) None of the above​

Answer 1

Given that the time-displacement graph of a particle is parallel to the time-axis. That means if the distance-time graph of the object is parallel to the time axis then the particle has not covered any displacement with change in time. i.e. the particle is at rest.
