A particle is moving along X-axis under ...

A particle is moving along X-axis under a force such that its position -time graph is as shown in figure.

As the particle passes position (1):

A

it is moving along negative X-direction with a speed that is increasing with time

B

it is moving along positive X-direction with a speed that is decreasing with time

C

it is moving along negative X-direction with a speed that is decreasing with time

D

it is moving along positive X-direction with a speed that is increasing with time

Text Solution

Verified by Experts

The correct Answer is:
D
If `(dx)/(dt)` slope of `x - t` curve is zero. Then particle will be at rest.
If `(dx)/(dt) gt 0` velocity is `+ve`
If `(dx)/(dt) lt 0` velocity is `-ve`
