An electrometer consists of two conducting spheres, each with a mass of 2.5 g attached by very thin (massless) conducting wires of length 5.3 cm.  The electrometer is initially uncharged (left) and the spheres hang straight down touching each other. A charged object is brought into contact with the charging pin transferring equal charges of +q to each sphere. Once charged (right), the spheres repel each other and hang at an angle of 10 . What is the magnitude of the charge on each sphere?
