Two particles are moving in different circles in same plane with different angular velocities as shown in figure. At t = 0, initial positions of particles A and B are shown by dots on the respective circles. Initial distance between particles is 1m. Particle A move anticlockwise in the first circle whereas B moves clockwise in the second circle. Angle described (rotated) by A and B in time 't' are theta_(A)=((pi)/2t) and theta_(B)=(pit) respectively. here theta is in radian and t is in second. Radius of each circle is shown in diagram. At time t=2 second, the angular velocity of the particle A with respect to the particle B is
