[SOLVED] negative rod to uncharged metal ball:
If a negatively charged rod is held near an uncharged metal ball, the metal ball:
1. becomes positively charged.
2. becomes polar.
3. Effect cannot be determined.
4. becomes negatively charged.
5. is unaffected.
I guessed number 4, thinking that if the negative rod touched the neutral ball, the ball would gain electrons ( since its easier to gain and lose electrons - very very difficult and rare for an object to lose or gain protons )
This would make the ball negative but I was wrong... what's the catch here?
