y-x curve at an instant for a wave trave...

`y-x` curve at an instant for a wave travelling along `x-`axis on a string is shown. Slope at the point `A` on the curve, as shown, is `tan 53^(@)`.

A

Transerse velocity of the particle at point A is positive if the wave is travelling along positive x axis

B

transverse velocity of the particle a t point A positive if the wave is travelling along negative x axis of the particle at point A

C

Magnitude of transverse velocity of the particle at point A is greater then wave speed

D

Magnitude of transverse velocity on a string of the particle at point A is lesser then wave speed
