The gravitational force of attraction between two objects is x, Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become:
A. x/4 B. x/2
C. 2x D. 4x
We know, F = G * M * m/d2
Now after keeping the masses of the object constant and decreasing the distance between them to half, than the previous, we get:
F’ = G * M * m/ (d/2)2
F’ = 4 (G * M * m/d2)
F’ = 4F

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:
