Question

object attracts object be with a gravitational force of 5 N from a given distance if the distance between the two objects is reduced in half what will be the change force of attraction between them

Answer 1

\[F=\frac{ GMm }{ r^2 }\]

G is a constant, and M and m are the mass of the objects. these don't change, but the distance (r) does. notice what happens to the equation when cut the distance in half

(replace r with (1/2)r)
