A particle starts from origin and moving along `x-`axis. Whose `v-t` graph is as shown . Choose the INCORRECT statement :
.

A

At point `L` particle is speeding up.

B

At point `M`particle is moving in positive `x-`direction.

C

At point `N` particle is speeding up.

D

At point O particle is rest.

Text Solution

Verified by Experts

The correct Answer is:
D
(1) At ` L`,`(dv)/(dt)` is positive
(2) Till M, area under `v-t` curve is positive and velocity is `+ve` . So particle is going in `+x` direction
(3) At `N`,`(dv)/(dt)` is negative , so, velocity will increase in magnitude in negative direction.
(4) At `O`,particle is moving with constant velocity.
