# 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   Option 1) acceleration Option 2) momenta Option 3) potential energy Option 4) kinetic energy

As we learnt in

Definition of work by constant force -

$W=FS\cos \Theta$

- wherein

The product of  magnitude of force $\left ( F \right )$ magnitude of displacement $\left (S \right )$ and cosine of the angle between them  $\left (\Theta \right )$

Acceleration due to gravity is independent of Mass of the body.

Option 1)

acceleration

Option is correct

Option 2)

momenta

Option is incorrect

Option 3)

potential energy

Option is incorrect

Option 4)

kinetic energy

Option is incorrect
