A mass suspended from a vertical spring performs S.H.M. of period 0.1 second. The spring is unstretched at the highest point of suspension. Maximum speed of the mass is (Gravitational acceleration $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )

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

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

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

$\pi \mathrm{m} / \mathrm{s}$

' $P$ ' and ' $Q$ ' are fixed points in same plane and mass ' $m$ ' is tied by string as shown in figure. If the mass is displaced slightly out of this plane and released, it will oscillate with time period $(\mathrm{PQ}=2 \mathrm{~d}, \mathrm{PR}=\mathrm{QR}=\mathrm{L})(\mathrm{g}=$ gravitational acceleration)
