The figure below is a representation of a simple harmonic progressive in the negative X-axis, at a given instant. The direction of the velocity of the particle at stage P in the figure is best represent by the arrow.

A

`vec(P)A`

B

`vec(P)B`

C

`vec(P)C`

D

`vec(P)D`

Text Solution

Verified by Experts

The correct Answer is:
a
`v_(p)=-v((dy)/(dx))`
here c is negative and `dy//dx` is positive at point `P`. Hence `V_(p)`is positive. So `P` is moving upward.
