A transverse sinusoidal \( y \) wave moves along a string in the positive \( x \)-direction at a speed of \( 10 \mathrm{~cm} / \mathrm{s} \). The wavelength of the wave is \( 0.5 \mathrm{~m} \) and its amplitude is \( 10 \mathrm{~cm} \). At a particular time \( t \), the snap-shot of the
P
W wave is shown in figure. The velocity of point \( P \) when its displacement is \( 5 \mathrm{~cm} \) is (2008) (a) \( \frac{\sqrt{3} \pi}{50} \hat{\mathbf{j}} \mathrm{m} / \mathrm{s} \) (b) \( -\frac{\sqrt{3} \pi}{50} \hat{\mathbf{j}} \mathrm{m} / \mathrm{s}(\mathrm{c}) \frac{\sqrt{3} \pi}{50} \hat{\mathbf{i}} \mathrm{m} / \mathrm{s} \) (d) \( -\frac{\sqrt{3} \pi}{50} \hat{\mathbf{i}} \mathrm{m} / \mathrm{s} \)
