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 figure. The velocity of point $P$ when its displacement is $5 cm$ is

Particle velocity v p ​ = − v (slope of y − x graph) Here, v = + v e , as the wave is travelling in positive x -direction. Slope at P is negative. ∴ Velocity of particle is in positive y ( + j ​ ) direction. ∴ correct option is (a).
