Question

How does the force of gravitation between two objects change when the distance between them is reduced to half?​

Answer 1

Let there be two bodies of masses m1 and m2 and let the distance between them be r. The gravitational force F between them would be given by

$f = g \times \frac{m1 \times m2}{ {r}^{2} }$

Let the distance between them be halved by two. The gravitational force between them would now be given by
