An iron sphere of mass 10 kg has the same diameter as an aluminium sphere of mass 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

Text Solution

Verified by Experts

The correct Answer is:
A

When both spheres are dropped simultaneously from a tower, they have same acceleration. Becuause, during free fall acceleration of body becomes equals to `(g=9.8m//s^(2))` and 'g' depends on mass of earth and radius of earth `(i.e.,g=(GM_(2))/(R_(e)^(2)))`
