Question

Object A attracts object B with a gravitational force of 10 newtons from a given distance. If the distance between the two objects is doubled, what is the changed force of attraction between them?

Answer 1

if the distance is doubled then force of attraction due to gravity would undoubtedly be 1/4 times of he previous one
as force is inversely proportional to square of distance..
\[GMaMb/r^{2}\]
now if r is made 2r then force would be
\[GMaMb/2r^{2}\]
or we could write it as \[GMaMb/4r^{2}\]
here G=gravitational constant and Ma=mass of object A and Mb=mass of object B
hope u got the answer!!
