Gravitation Problem :(
Question:
Find the point between Earth and the sun at which an object can be placed so that the net gravitational force exerted by Earth and the sun on an object is zero.
Earth's mass: 5.98x10^24 kg
Earth's radius: 6.38x10^6 m
Sun's mass: 1.991x10^30 kg
Sun's radius: 6.96x10^8 m
I know I have to use the equation for gravitational force:
F=G(m1m2/r^2)
So at this point I'm lost. Do I make up a mass for the object and figure out the force for Earth and the sun separately? Do I put the values for the sun and Earth into one equation and set the force equal to zero? Any help would be greatly appreciated :D
