Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, nonconductive walls, the bead move, and at equilibrium the line joining the balls is horizontal and the distance between them is R (see figure). Neglect any induced charge on the hemispherical bowl. Then the charge on each bead is : (here K = 1/ 4πε0)
