Solution

The correct option is C

1: 1: 1


The value of ‘g’ does not depend on the mass of the body. Hence, if different objects of different masses are simultaneously dropped from a height, all of them will reach the ground simultaneously if the effect of air is neglected. Path is frictionless and objects are falling freely due to gravity from same height, thus all the masses will have same velocity.
