Particle A moves with 4m/s along positive y-axis and particle B moves along a circle a2 + y? = 4 (anticlockwise) with constant angular velocity w = 2rad/s. At time t=0, particle B is at (2m,0) and velocity is parallel to j. Then S. (A) magnitude of relative velocity between them at time tis (8 sin t) m/s (B) magnitude of relative velocity between them is maximum at t = 7s
