Question
Find the gravitational force acting on the Sun by the Earth.
Given: Mass of the Sun = 1.99 * 1030 kg
Mass of the Earth = 5.98 * 1024 kg
Radius of the Sun = 6.96 * 108 m
Radius of the Earth = 6.37 * 106 m
Distance between the Sun and the Earth = 1.50 * 1011 m
G = 6.67 * 10–11 N m2 kg–2

Just use the formula
F = GMm/r^2
Disregard the data about the sizes of the bodies. You have their masses and the separation, and G.
So, plug in the numbers.

use the formula g=Gm1m2/r^2
G=6.67 x 10^-11 N
G=6.67 x 10^-11 N
