Question 4
An iron sphere of mass 10 kg has the same diameter as an aluminium sphere of mass is 3.5 kg. Both spheres are dropped simultaneously from a tower. When they are 10 m above the ground, they have the same

(a) acceleration
(b) momenta
(c) potential energy
(d) kinetic energy

Answer 1

(a) acceleration

The acceleration of both the bodies are same as the acceleration due to gravity, hence both the bodies will have the same acceleration. The mass of both the body is different, hence kinetic, potential energy and momenta will be different.
