Consider two metallic rods mounted on insulated supports. One is neutral, another positively charged. The charged rod is brought close to the neutral one (no touching!) and at this time the neutral rod was briefly grounded (for instance, touched by your hand).

Part (a) What would be resulting charge (if any) on initially neutral rod?

1) There is not enough information given to be able to answer.

2) It will be positively charged.

3) It will be negatively charged.

4) It will remains neutral.
