Two particles A and B are moving along concentric circles of radii 3 m and 4 m respectively. Angular speed of A is π/3 rad-min–1 and angular speed of B is π/6 rad-min+ . At t = 0 they cross x-axis simultaneously as shown. What is the separation between them after 3 minutes ?
(A) 7 m
(B) 5 m
(C) 1 m
(D) 0.5 m
