A particle executes a linear S.H.M. In two of its positions the velocities are $\mathrm{V}_1, \mathrm{~V}_2$ and accelerations are $\mathrm{a}_1$ and $\mathrm{a}_2$ respectively $\left(0

$\frac{V_1^2-V_2^2}{a_1-a_2}$

$\frac{V_2^2-V_1^2}{a_1-a_2}$

$\frac{V_1^2-V_2^2}{a_1+a_2}$

$\frac{v_2^2-v_1^2}{\left(a_1^2+a_2^2\right)}$

A mass $x$ gram is suspended from a light spring. It is pulled in downward direction and released so that mass performs S.H.M. of period T. If mass is increased by Y gram, the period becomes $\frac{4 \mathrm{~T}}{3}$. The ratio of $\mathrm{Y} / \mathrm{x}$ is

$7: 9$

$5: 4$

$3: 2$

$8: 7$
