The velocity of a particle moving with simple harmonic motion, at any instant is given by (where $$\omega $$ = Displacement of the particle from mean position)
A
$$\omega \sqrt {{{\text{x}}^2} - {{\text{r}}^2}} $$
B
$$\omega \sqrt {{{\text{r}}^2} - {{\text{x}}^2}} $$
C
$${\omega ^2}\sqrt {{{\text{x}}^2} - {{\text{r}}^2}} $$
D
$${\omega ^2}\sqrt {{{\text{r}}^2} - {{\text{x}}^2}} $$
Correct Answer: $$\omega \sqrt {{{\text{r}}^2} - {{\text{x}}^2}} $$
