A particle moving parallel to x-axis as ...

A particle moving parallel to x-axis as shown in fig. such that at all instant the y-axis component of its position vector is constant and is equal to 'b'. Find the angular velocity of the particle about the origin when its radius vector makes angle `theta` from the axis.

Text Solution

Verified by Experts

`therefore omega_(PO)=(v sin theta)/((b)/(sin theta))=(v)/(b)sin^(2)theta`
