Are you serious? Dammit! What the hell is the buoyancy definition then? All we learned about buoyancy was Archimedes Principle. As I stated: F = rho*V*g
Please explain how you got to your conclusion because I can't as I've said. There are too many unknowns or I'm just blind and am not seeing...

I got this problem on my midterm and I'm pissed off that I...
I'm all for the FBD idea but I don't know how to get the angles. If they were provided in the equation that would be cake but I can't remember there being a way to calculate them. Sorry for being so noob I haven't used trig in a long time and it's over a year since I've taken a physics class.
thanks for the welcome. I figured that the spheres would probably attract each other somewhat and I calculated the gravitational attraction (I believe) in my attempt at the solution please correct me if I am wrong tho. I am unsure how to calculate how far 6.67x10^-7 N would push each sphere in...
