Three different objects of masses m 1 , m 2 and m 3 are allowed to fall from rest and from the same point O along three different frictionless paths. The speeds of the three objects on reaching the ground will be in the ratio of (a) m 1 : m 2 :m 3 (b) m 1 : 2m 2 :3m 3 (c) 1:1:1 (d) m 1 m 2 m 3

(c)

The speed of an object, falling freely due to gravity, depends only on its height and not on its mass. Since the paths are frictionless and all the objects fall through the same height, therefore, their speeds on reaching the ground will be in the ratio of 1 : 1 : 1.
