## Question On Gravitational Force

First, the homework:-

Gravitational force between any two masses is directly proportional to the product of the masses & inversely proportional to the square of the distance between them.

F = G (M1 * M2) / r^2

Let us consider that two masses of 1kg & 100kg are kept at a distance of 100 m from the earth. Obviously, as the distance (r) is same for both the masses, from the earth is same, we can neglect it for the time being.

According to formula, the force exerted on 100Kg mass will be 100 times more than the force exerted on 1kg mass. Therefore, it should come down to earth faster 😁 & reach the ground earlier than the 1kg mass, what say?

But we all know that both the masses will hit the ground at the same time. What's wrong in this argument?

Its easy! Use common sense & answer!
