Question

the gravitational force of attraction between two bodies at a distance x is 20 Newton what will be the force of attraction between them if the distance between them is made to X ​

Answer 1

Answer:

40newton is the answer

Answer 2

According to Newton's law of gravitation,

The force of attraction F 1 / r^2

-We use only this proportionality because the bodies are the same in both cases, therefore its the same masses

-Only the distance between the masses is changing from x to 2.x

-From the proportionality, we have

F1/F2 = (r2^2) / (r1^2)

taking F1 = 20 N

           r1 = x

           r2 = 2.x

we solve for F2

-F2 will evaluate to 5 N
