1. The problem statement, all variables and given/known data Two identical, uniform, frictionless spheres, each of weight W , rest in a rigid rectangular container as shown in the figure. Find, in terms of a ratio to W, the forces acting on the spheres due to the container surfaces and one another, if the line of centers of the spheres makes an angle of 45° with the horizontal. Normal force from the left side of the container? [PLAIN]http://img260.imageshack.us/img260/7907/1368b.jpg [Broken] 2. Relevant equations newtons 3rd law(not realy an equation) 3. The attempt at a solution Looking at the picture i believe the force from the left side of the container will be equal to the force in the x direction applied to ball 2 from ball 1, so i set the force to be W*cos45, however that is not correct.
