Question

Two spheres of same size, one of mass `2 kg` and another of mass `4 kg`, are dropped simultaneously from the top of Quata Minar `(height = 72 m)`. When they are `1 m` above the ground, the two spheres have the same.
A. momentum
B. kinetic energy
C. potential energy
D. acceleration

Answer 1

Correct Answer - D
When two spheres are dropped they will acquire the same acceleration which is due to gravitational effect. And also the acceleration due to gravity is independent of mass of the body. Hence, the two spheres have the same acceleration.
