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
$$\frac{1}{4 \pi} \mathrm{m} / \mathrm{s}$$
C
$$\frac{1}{2 \pi} \mathrm{m} / \mathrm{s}$$
D
$$\pi~ \mathrm{m} / \mathrm{s}$$

A body performs S.H.M. under the action of force '$$\mathrm{F}_1$$' with period '$$\mathrm{T}_1$$' second. If the force is changed to '$$\mathrm{F}_2$$' it performs S.H.M. with period '$$\mathrm{T_2}$$' second. If both forces '$$\mathrm{F_1}$$' and '$$\mathrm{F_2}$$' act simultaneously in the same direction on the body, the period in second will be

A
$$\frac{T_1+T_2}{T_1 T_2}$$
B
$$\frac{T_1^2+T_2^2}{T_1 T_2}$$
C
$$\frac{\mathrm{T}_1 \mathrm{~T}_2}{\sqrt{\mathrm{T}_1^2+\mathrm{T}_2^2}}$$
D
$$\frac{T_1 T_2}{T_1+T_2}$$
