An iron sphere of mass 10 kg has the same diameter as an aluminium sphere of mass 3.5 kg. Both the spheres are dropped simultaneously from a tower. When they are 10 m above the ground, they have the same :
पर्याय
acceleration
momentum
potential energy
kinetic energy
उत्तर
Momentum, potential energy and kinetic energy depend on the mass of the body. So, the answer is acceleration as it is independent of mass.
Therefore, the answer is,
(a) Acceleration
