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? multiple choiceAll of the added charge is distributed uniformly over the surface of the ball.All of the added charge has vanished, and the ball is again electrically neutral.All of the added charge has moved to the center of the ball.The added charge is still located at or very near the north pole of the ball.The added charge is performing a simple harmonic oscillation on a straight line between the south and north poles of the ball.

Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then:negative and distributed uniformly over its surface.negative and appears only at the point on the sphere closest to the point chargenegative and distributed non-uniformly over its entire surface of the spherezero

When is the net charge positive, and when is it negative?

Based on your experiments with the John Travoltage simulation (PhET), select the best answer:When a very small amount of negative charge is built up on John's body, _____ static discharge occurs when his finger gets close to the metal doorknob. Group of answer choicesa largea reverseno

What will happen when we put a positively charged plate near conductors?

An uncharged conductor is brought in contact with a positively charged body. What is the nature of charge acquired by the conductor?
