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