Question

A big stone and small are dropped from the roof of the house at the same time. Which one will reach the ground first?

Answer 1

we know that acceleration due to gravity

=). g = GM/R^2 -----------(1)

where M = mass of earth
=) R = radius of earth.
=) G = universal gravitational constant.

from equation ( 1) we can see that acceleration due to gravity does not depend on mass of object , it only depends on the mass and radius of earth.

=) so when small stone and big stone are dropped acceleration of both the stones are same so both reaches the ground at the same time.

Hope it will help u

Answer 2

When big stone and small are dropped from the roof of the house at the same time then both will reach at same time .

<Reason>
We all know that     g = GM/ $R^{2}$
where G= Universal gravitational constant
           M= Mass of earth 
           R= Radius of earth 
           g = acceleration due to gravity

From above It is concluded that g does not depend upon mass of object , which concludes that both stones will reach earth surface / ground at same time.
