The radius of cirlcue, the period of revolution, initial position and sense of revolution are indicated in the figure. y-projection of the radius vector of rotating particle P is :A. `y(t)=3cos ((pit)/(2))`, where y in mB. `y(t)=-3 cos 2pit`, where y in mC. `y(t)=4sin((pit)/(2))`, where y in mD. `y(t)=3cos ((3pit)/(2))`, where y in m |

Answer» Correct Answer - A `T=(2pi)/(omega)=4, omega=(pi)/(2)` y co-ordinate starts from maximum So `y=A cos (omegat)` `Y=3cos((pi)/(2)t)` |
