Solve Gravitation Problem between Earth & Sun

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

take any arbitrary mass m and go from there.

So I found the sun and the Earth's respective gravitational forces...
How would I go about finding the point where they equal zero?

Show us your calculations.

this question is complete, for this you should must knew about the distance between sun and earth...
as this distance keeps changes therefore first notify the exact distance for which you want the answer.ok
well according to me ans should be
(y-x)(332943.1438)=x

where y means distance between Earth and sun

and x means distance of object from sun...
therefore after putting value of "y" you will get value of "x" and after it you can easily find distance between object and Earth too
