★ 5th Question

If two stones of 150g and 500g are dropped from a height, which stone will reach the surface of the Earth first and why? Explain your answer.​

Answer 1

Heya mate....

☢️The stone having a weight a 500 gm will reach the surface of first because if we denfine gravity,it is the force of attraction between two objects due to to their masses. So,the more that mass,the faster the gravity will pull the object towards it and vice versa..

Hope it helps uh ❤️

Answer 2

$\underline\bold{Answer:-}$

It was Galileo, who first time demonstrated and depicted that the acceleration of an object falling freely towards earth does not depend on the mass of an object.

• It can be verified by universal law of gravitation.

》Let an object of mass m is allowed to fall from a distance of hour from the centre of the Earth.

The gravitational force 'F' = (GMem) / R² [Me = mass of the earth).

The force acting on the stone , f = ma

Therefore, m×a = (GMem)/ R ²

=> a = GMe/R ²

》 So acceleration in an object falling freely on the earth and depends on the mass of the earth and height of object from the centre of the earth.

So , stones of masses 150g and 500g will reach the earth's surface together.
