success Posted December 3, 2007 Posted December 3, 2007 Tough Physics Question Three uniform spheres are located at the corners of an equilateral triangle. Each side of the triangle has a length of 1.48 m. Two of the spheres have a mass of 2.18 kg each. The third sphere (mass unknown) is released from rest. Considering only the gravitational forces that the spheres exert on each other, what is the magnitude of the initial acceleration of the third sphere?
Mr Skeptic Posted December 3, 2007 Posted December 3, 2007 The mass of the third sphere doesn't matter, because the force will be proportional to the mass, and hence the initial acceleration will be the same regardless of the mass.
iNow Posted December 3, 2007 Posted December 3, 2007 Do you happen to post as Finns14 over here, where this exact question worded the same way appears? http://www.physicsforums.com/showthread.php?t=112713 Or... are you trying to get some google strength for the URL in your signature, and you're just copying stuff from other seemingly random internet sites and posting it here as your own?
