The maximum velocity of a particle performing S.H.M. is '$$\mathrm{V}$$'. If the periodic time is made $$\left(\frac{1}{3}\right)^d$$ and the amplitude is doubled, then the new maximum velocity of the particle will be

A
$$\frac{\mathrm{V}}{6}$$
B
$$\frac{3 \mathrm{~V}}{2}$$
C
$$3 \mathrm{~V}$$
D
$$6 \mathrm{~V}$$

A child is sitting on a swing which performs S.H.M. It has minimum and maximum heights from ground $$0.75 \mathrm{~cm}$$ and $$2 \mathrm{~m}$$ respectively. Its maximum speed will be $$\left[\mathrm{g}=10 \frac{\mathrm{m}}{\mathrm{s}^2}\right]$$

A
$$\sqrt{1.25} \mathrm{~m} / \mathrm{s}$$
B
$$\sqrt{12.5} \mathrm{~m} / \mathrm{s}$$
C
$$5 \mathrm{~m} / \mathrm{s}$$
D
$$25 \mathrm{~m} / \mathrm{s}$$
