Integrated Concepts
(a) In Figure 18.59, four equal charges q lie on the corners of a square. A fifth charge Q is on a mass m directly above the center of the square, at a height equal to the length d of one side of the square. Determine the magnitude of q in terms of Q ,m , and d, if the Coulomb force is to equal the weight of . (b) Is this equilibrium stable or unstable? Discuss.
