Estimating Charge Two hard rubber spheres of mass ~30 g are rubbed vigorously with fur on a dry day. They are then suspended from a rod with two insulating strings of length 10 cm. They are observed to hang at equilibrium, 19º from vertical, as shown in Fig. 22-41. Estimate the amount of charge that is found on each sphere. хс 3 cm Figure 22-41
