Question
Read the following and select one choice:Please do not just answer the question, offer an explanation.
Two uncharged metal balls, X and Z, stand
on insulating glass rods. A third ball, carrying
a positive charge, is brought near the ball Z
as shown in the figure. A conducting wire is
then run between X and Z and then removed.
Finally the third ball is removed.
When all this is finished:
3. ball X is positive and ball Z is neutral.
4. ball X is negative and ball Z is neutral.
5. ball X is positive and ball Z is negative.
7. ball X is negative and ball Z is positive.
8. ball X is neutral and ball Z is positive.
9. ball X is neutral and ball Z is negative.
10. balls X and Z are both negative, but ball
X carries more charge than ball Z.
Explanation / Answer
During electrification when the negative charge placed near to the Z ball and which is connected to the ball X then the electrons moves away from the surface where the negative charge nearer so finally the ball Z becomes positive and X becomes negative. 10. ball X is negative and ball Z is positive
