A particle performs linear S.H.M. At a particular instant, velocity of the particle is ' $u$ ' and acceleration is ' $\alpha$ ' while at another instant, velocity is ' $v$ ' and acceleration is ' $\beta$ ' $(0<\alpha<\beta)$. The distance between the two positions is

$\frac{u^2-v^2}{\alpha+\beta}$

$\frac{u^2+v^2}{\alpha+\beta}$

$\frac{u^2-v^2}{\alpha-\beta}$

$\frac{u^2+v^2}{\alpha-\beta}$

A particle executing S.H.M. has velocities ' $\mathrm{V}_1$ ' and ' $\mathrm{V}_2$ ' at distances ' $x_1$ ' and ' $x_2$ ' respectively, from the mean position. Its frequency is

$\frac{1}{2 \pi} \sqrt{\frac{V_1^2-V_2^2}{x_1^2-x_2^2}}$

$2 \pi \sqrt{\frac{x_1^2-x_2^2}{v_1^2-V_2^2}}$
