Question

Please give your answers with steps

Answer 1

Force is directly proportional to the two bodies with mass m1 and m2 and is inversely proportional to the square of distance between them.
F ~ (m1*m2)/d^2
F=G*m1*m2/d^2
Where G is the universal gravitational constant!

I hope my ans helps you
