A transverse sinusoidal wave moves along a string in the positive $x$ -direction at a speed of $10 cm s^{- 1}$ . 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 the point $P$ when its displacement is $5 cm$ is.
