Question

9. Two bodies A and B rotate about an axis such that
angle ¢1, (in radians) covered by the first body is pro-
portional to the square of time and ¢2, (in radians)
covered by the second body varies linearly. At t = 0,
¢1,= ¢2, = 0. If A completes its first revolution in √π s
and B needs 4π s to complete half revolution, then
angular velocity w1:w2, at t= 5 s is in the ratio
(A) 4:1
(B) 20:1
