Then rub the glass rod on the silk to charge the rod positively (hence to charge piece of silk negatively). 2. gneill said: Almost. On being charged the spheres, which were originally in contact, take up positions with their centers 5 cm apart. It may be possible to quickly venture into other areas of the ruins without arousing his attention, but the benefits of so tremendous risk seem minimal. Now, here we will derive the formulas related to this equilibrium condition. If they are far apart the capacitance is proportional to: Solution: The capacitance between two objects is, by definition, C = Q / V, where Q and -Q are charges placed on the two objects and V is the difference of potentials between the two objects produced by the two charges. The older man turned them around and Harry's hands trembled as he bent over the counter. In this problem, do not assume the balls are point charges. .
