A particle is performing SHM aong x-axis,such that its velocity is `v_1` when its displacement from mean position is `x_1` and `v_2` when its displacement from mean position is `x_2`.Time period of oscillation is

Options

A. `1/2 pi sqrt((x_2-x_1)/((v_1-v_2))`
B. `2pi sqrt(((x_1^2+x_2^2))/((v_2^2+v_1^2))`
C. `2pi sqrt(((x_1^2-x_2^2))/((v_2^2-v_1^2))`
D. `2pi sqrt (((x_1x_2-x_1^2))/((v_1v_2-v_1^2)`
