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 (6) :A. it is moving along positive X-direction with a speed that is increasing with timeB. it is moving along positive X-direction with a speed that is decreasing with timeC. it is moving along negative X-direction with a speed that is increasing with timeD. it is moving along negative X-direction with a speed that is decreasing with time

Answer» Correct Answer - 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`
