Newton's law of universal gravitation describes the gravitational force between two objects (like the sun and the earth or the earth and a satellite or the earth and its moon) gravitational force g = 6.67 × 10-11 m3 kg-1 s-2 used in the formula, f = g (m1 * m2) r2 where f is the gravitational force between two masses, ...

What's the ques ?? Ur ques is incomplete...
whatever u wrote is true.... so where's the ques !!!!

Question:
Find the gravitational force between the
Sun and the Earth.
Given Mass of the Sun = 1.99x1030 kg
Mass of the Earth = 5.98x1024 kg
The average distance between the Earth
and the Sun = 1.5x1011 m.
Answer:
We can use Newton’s law of universal gravitation.
Which is F = Gm1m2/r^2
Where the Force (F) will be in Newtons.
G is the “Universal Gravitational Constant”. G = 6.67 × 10^-11 N m^2 kg^-2
M1 is the first mass, the Sun. Mass of the Sun = 2 x 10^30 kg
M2 is the second mass, the Earth. Mass of the Earth = 6 x 10^24 kg
DR is the distance between the two objects. Distance from the Earth to the Sun = 1.5 x 10^11 metres
F = Gm1m2/r^2
F = G x 2 x 10^30 x 6 x 10^24/ [1.5 x 10^11] ^2 = 6.7 x 10^11 N
