Two particles A and B are moving in a horizontal plane anitclockwise on two different concentric circles with different constant angular velocities `2omega` and `omega` respectively. Find the relative velocity (in m/s) of B w.r.t. A after tome `t=pi//omega`. They both start at the position as shown in figure `("Take" omega=3rad//sec, r=2m)`
