A neutral pith ball joined by copper wire to a negative rod acquires a charge that is:
ANeutral
BMagnetic
CNegative
DPositive
Answer & Solution
Correct answer: C. Negative
1. Copper carries charge from the rod to the ball.
2. The ball takes on the same kind of charge as the rod.
3. So it becomes negative.
