Question

The force F of attraction between two bodies varies jointly as the weights of the two bodies and inversely as the square of the distance between them. Express this fact as a variation using c as a constant. Use M1 and M2 for the weights of the two bodies.

Answer 1

i think That's Newton's Law of Gravitation. Since it varies directly with M1 and M2 and inversely with the square of the distance, we have: FαM 1 M 2 d 2 Where alpha means that Force is proportional to that. But we need a constant, known as proportionality constant, to make the equation true. So: F=cM 1 M 2 d 2 but is incorrec
