Science Physics Q&A Library You have two lightweight metal spheres, each hanging from an insulating nylon thread. The larger sphere is positively charged with charge, connected at the bottom so that the metal rod and rails form a loop that has a resistance of 52 ohm. It slid from his body and collapsed on the floor. What is the charge on the pith balls? The force is inversely proportional to the square of the distance between the charges, and is directed along the straight line that connects their centers. If the two spheres are attached by a very long conducting thread, what is the final distribution of charge on the two spheres? One may simplify further by introducing expression for q from the electrostatic force equation and may do more arithmetic For my point here, this much is enough, it is clear that dq/dt depends on dx/dt (it is vivid in the question too).
