Question

the force of attraction between two bodies at a certain separation is 10 N. what would be the force of attraction between them if the separation between them is reduced to half? ​

Answer 1

Explanation:

as F is inversely proportional to r^2 the force between them increases 4 times the original force

Answer 2

Answer:

40 N.

Explanation:

The force of attraction is normally gravitational force between the two bodies. Considering an ideal situation the Universal Law of Gravitation states that F is  proportional to 1/$r^{2}$. Therefore, when r becomes r/2 F becomes 4F which is 40N.
