Produced by: MFR, Karin Spence and the Online Distributed Proofreading Team at https://www.pgdp.net (This file was produced from images generously made available by The Internet Archive) If a plastic rod rubbed with fur is made to touch two small pith balls (now-a-days we can use polystyrene balls) suspended by silk or nylon thread, then the balls repel each other [Fig. It is made up of one or two small non-conductive balls that are suspended from the hook of an enclosed stand using silk or linen thread. In this problem, do not assume the balls are point charges. A neutral metal ball has a balanced number of electrons. We will use a video to analyze the dependence of the magnitude of the Coulomb force between two electrically-charged metal spheres on the charge of one of the spheres. Draw a free-body diagram for each ball: Suppose the charge on the second ball is reduced slightly, so that it is less than that on the first ball. 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. Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -2.0 C; sphere B carries a charge of -6 . Please note that the 416 mm (16 3/8") c.c.

Is it possible that after the spheres touch, they will cling together? Note that Newton's third law (every force exerted creates an equal and opposite force) applies as usualthe force on is equal in magnitude and opposite in direction to the force it exerts on . If a glass rod is rubbed with silk, the silk rubs some electrons off the rod. The spheres are brought to within 15.0 cm of each other, as shown. After bringing them in contact with each other, they again placed at the same distance apart. 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. Sm8 21 . Two equally charged spheres of mass 'm', suspended by two silk thread of length l, the spheres are separated by distance x (x<*{. The hanging ball should be centered on a line with the sliding balls. Explain. Two small equally charged spheres, each of mass $m$, are suspended from the same point by silk threads of length $l$. Then calculate the distance x in the equilibrium state. I ascertained that these effects could only have rise from the deception of those holding the rod or the pendulum, or, may be, from some diabolic impulsion, or, more likely still . PHY2049 R. D.

Five styrofoam balls are suspended from insulating threads. The beads shown here and are mostly of the common three eyed type. Pass the thread from 2 of the spheres through a small loop and tie off the thread equally above the loop. Sm8 21 . If the spheres maintain a constant distance x, while they are kept apart by the repulsive Coulomb force, then there is no charge loss. The charge on sphere A is +5.0 x coulomb and the charge on sphere B is +3.0 x 104 coulomb. Two metal spheres are hanging from nylon threads. Two similar conducting balls of mass m are hung from silk threads of length L and carry similar charges q as shown in the figure. Best Answer. Q.
