The earth has a mass = 5.98 X 10^24 kg and the sun has a mass = 1.99 X 10^30 kg. They are separated, center to center, by r= 93 million miles = 150 million km.
What is the size of the gravitational force acting on the earth due to the sun?
Very confused by this problem. May someone walk me through the problem step by step? Thank you

F =G•m1•m2/R²
the gravitational constant G =6.67•10^11 N•m²/kg²,
m1 = 5.98 X 10^24 kg
m2 = 1.99 X 10^30 kg
R=1.5•10^11 m
