Question

Two particles are placed at some distance and the magnitude of gravitational force between them is f. If the mass of each of the two particles is doubled, keeping the distance between them unchanged, the new value of gravitational force, in terms of f, between them will be:

Answer 1

The gravitational force between 2 bodys decreases with distance between the two bodies.

This formula describes the force between 2 bodies with mass m1 and m2, distance r.G is the gravitational constant. The distance, r, has an inverse square relationship to the force. If the two bodies were twice as far, the force would be 4 times less. In your case, if they were twice as near (or the distance between them is halved), the force increases by a factor of 4. You would also increase the force by this factor if you increased the product of the masses by 4.

Answer 2

Explanation:

Pressure is scalar quantity which is defined as force per unit area where the force acts in a direction perpendicular to the surface.
