Question

Which way do electrons within the rectangular rods move when a positively-charged rod is

brought near a positively-charged rod?

Answer 1

The "like/similar" charges REPEL each other and the opposite charges ATTRACT each other. (sometimes allowing for an exchange of electrons.) THIS GOES FOR 2 NEGATIVELY charged rods, also.

Answer 2

You meant "Negative-charged rod"?

If you did then here's the answer.

Away.

Step-by-step explanation:

Since, the rod and Balloon both are negatively charged, and we know that like charges repel each other so, the electrons in the rod tend to move away from negatively charged balloon.
