Question
A transverse sinusoidal wave moves along a string in the positive $x$-direction at a speed of $10 \mathrm{~cm} /$ s . The wavelength of the wave is 0.5 m and its amplitude is 10 cm . At a particular time t , the snapshot of the wave is shown in figure. The velocity of point P when its displacement is 5 cm is
