Two positively charged spheres with equal mass m are placed on a circular ramp, which has a radius S. The left sphere has a charge q and the right sphere has a charge 2q. The charges repel each other until they reach equilibrium. At this point, the left sphere makes an angle of θL with the vertical, and the right sphere an angle θR. Assume the radii of the charged spheres are much less than S. You will need Newton, Laws and Coulomb's Law for this problem.
(a) Is the angle θL greater than, less than, or equal to the angle θR?
(b) If you measure the changes to be separated by a distance d, what is the value of g? Express you answer in terms of εo, m, d, the angles, and g, the acceleration due m gravity near the surface of the earth.
