Question

Two spheres of same size , one of mass `2 kg` and another of mass `4kg` are dropped smalltanausly from the top of is `72` as light tower When they are `1m` above the ground the two sphers have the same
A. momentum
B. kinetic energy
C. potential energy
D. acceleration

Answer 1

Correct Answer - d
When two sphere are dropped from rest , force of atraction due to earth acts on it Under the force of attraction they will acquire the same acceleration which is the to gravitational effect
`Also g = (GM)/(R^(2))`
in which acceleration due to gravity is independent of mass of the body .Hence , the two sphere have the same acceleration
