Question

Select One Option Correct from the following : A transverse sinusoidal wave moves along a string in the positive x direction at a speed of 10 cm/s. The wavelength of the wave is 0.5 m and its amplitude is 10 cm. At a particular time t, the snap-shot of the wave is shown in the figure. The velocity of point P when its displacement is 5 cm is
(A) $\frac{\sqrt{3}\pi }{50} \hat{j} m/s$
(B) $-\frac{\sqrt{3}\pi }{50} \hat{j} m/s$
(C) $\frac{\sqrt{3}\pi }{50} \hat{i} m/s$
(D) $-\frac{\sqrt{3}\pi }{50} \hat{i} m/s$
