Universal Law of Gravitation given by Newton is called Newton’s Law of Gravitation. This law states that, “Every object in the universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.”
Suppose two bodies A and B of mass m1 and m2 be at distance r from each other.
So, according to Newton’s law of gravitation,
And F …..2
Thus, combining equations 1 and 2 we get,
Where, G = Universal Gravitational Constant
G = Nm2kg-2

Universal law of gravitation states that every object exerts a gravitational force of attraction on every other object. If this is true, why don’t we notice such forces? Why don’t the two objects in a room move towards each other due to this force? (Picture)Lakhmir Singh & Manjit Kaur - Physics
Two particles are places at some distance from each other. If, keeping the distance between them unchanged, the mass of each of the two particles is doubled, the value of gravitational force between them will become:
A. 1/4 times B. 1/2 times
C. 4 times D. 2 timesLakhmir Singh & Manjit Kaur - Physics
