GENERAL KNOWLEDGE

Detailed explanation-1: -Gravitational force-an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

Detailed explanation-2: -Hence, we say that the force of attraction is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

Detailed explanation-3: -The gravitation force between the earth and object is called weight. It is also equal to the product of acceleration due to gravity and mass of the object.
