The sun has a mass of 1.99x10 30 kg the earth has a mass of 5.98x10 24 kg and is 1.496x10 11 m from the sun
a) Calculate the force of gravity acting on the eaarth by the sun
b) CAlculate the force of gravity acting on the sun by the earth

a and b are equal an opposite in direction.
force gravity=G M*m/d^2
