Question

a stone of mass 2 kg if falling from a certain height .find the force of attraction between the Earth and the stone ..also find the acceleration​

Answer 1

Answer:

If we drop a piece of stone from some height, the stone falls down towards the earth. Since the stone starts moving downwards (it is in motion),therefore a force must be acting on it. This force is due to attraction between the earth and the stone and it is called the gravitational force of earth (or gravity of earth). Thus, a stone dropped from a height falls towards the earth because the earth exerts a force of attraction (called gravity) on the stone and pulls it down.

Option A and C are also correct but they do not explain why the stone falls to the ground.

Answer 2

Answer:

Explanation:

F = mg = 2 x  -9.8 = -19.6 N

 The accelaration of the stone is g downwards , i.e , -9.8 m/s^2 , negetive sign is due to the downward direction
