Two spheres have the same positive charge Q and the same mass m. They hang vertically from the ceiling, each attached at the end of a string of length L. Because of the repulsive electric force between the two of them, the two spheres are at equilibrium at an angle from/to the vertical, as shown in the figure. (+Q L +Q (a) Analyze the forces acting on each sphere and draw a force diagram for each of them. (b) Find an expression for the charge Q on each sphere as a function of the given quantities L, m, g, and only. (Of course, your result will also contain the dielectric constant eb.)
