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)

at θ=180∘ we see that Fnet=2F0. (a) For the situation corresponding to curve 1 nonconductive walls the bead move Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless what is that ratio? what is the ratio of the charge of particle C to that of particle B (including sign)? (b) For the situation corresponding to curve 2
