Looks like you have the right equation and all the needed information. Check to make sure you are entering everything into your calculator properly. Simply solve the equation for R.
 
The formula is right, the answer is way, way off. How did you get it?
 
The G in the universal law of gravitation is not the same as g=9.81m/sec which is the acceleration due to gravity at the Earth's surface. It's 6.67*10^(-11)*m^3/(kg*sec^2). Try keeping track of units.

Oh, well then what is the G? because i have no clue.

I just edited to quote it. But you could look it up.
 
Righto.

24.713 is the answer right?

If you say 24.713m, I'll agree with that. Put units on things. If you'd done that you would have realized 9.8m/sec^2 couldn't be the G you want. Because you wouldn't have gotten an answer in meters.
 
S'ok. Word to the wise.
 
physicsbhelp, please don't delete all your posts after you have received help. It makes the thread totally unreadable, and useless to anyone else!
