A particle is suspended from a vertical spring which is executing S.H.M. of frequency $$5 \mathrm{~Hz}$$. The spring is unstretched at the highest point of oscillation. Maximum speed of the particle is $$(\mathrm{g} =10 \mathrm{~m} / \mathrm{s}^2)$$

A
$$\frac{1}{\pi} \mathrm{m} / \mathrm{s}$$
B
$$\frac{1}{4 \pi} \mathrm{m} / \mathrm{s}$$

$$\frac{1}{2 \pi} \mathrm{m} / \mathrm{s}$$
D
$$\pi~ \mathrm{m} / \mathrm{s}$$
