Find the force exerted on a particle on the Earth by the sun.
Homework Equations
F = - GMm/r2
r = distance between sun and particle
M = mass of sun
G = Gravitational constant
m = ?
The Attempt at a Solution
Should I be using the other mass as that of the earth, or that of a pebble? I think it is the pebble. I mean it's the force BY the sun ON the pebble, but I want to make sure.
