Two masses m1 and m2 are connected by light string, which passes over the top of a smooth plane inclined at 30º to the horizontal, so that one mass rests on the plane and the other hangs vertically as shown in fig. It is found that m1, hanging vertically can draw m2 up the full length of the plane in half the time in which m2 hanging vertically draws m1 up. Find m1 /m2 . Assume pulley to be smooth-
(A) 2/3
(B) 3/2
(C) 4/7
(D) 7/4
