Question

Concept Check 22.13 Suppose an uncharged solid steel ball, for example, one of the steel balls used in an old-fashioned pinball machine, is resting on a perfect insulator. Some small amount of negative charge (say, a few hundred electrons) is placed at the north pole of the ball. If you could check the distribution of the charge after a few seconds, what would you detect? 12 5 m is less curs by dif- lving for ri- a) All of the added charge has vanished, and the ball is again electrically neutral. t in Figure r = 0.250 b) All of the added charge has moved t to the center of the ball. c) All of the added charge is distributed uniformly over the surface of the ball. d) The added charge is still located at or very near the north pole of the ball s restin aced at e) The added charge is performing a simple harmonic oscillation on a straight line between the south and north poles of the ball.
