Question

select all the correct answers. a silk cloth gains electrons when rubbed over a glass rod. a different glass rod gains electrons when rubbed with rabbit fur. what will happen if the two charged glass rods approach one another and why? a. the rods will repel each other because they have unlike charges. b. there will be no reaction between the rods. c. the rods will attract each other because they are both positively charged. d. the rods will attract each other because they have unlike charges. e. the rods will repel each other because they have like charges.

Explanation:

When the silk cloth is rubbed on a glass rod, the glass rod loses electrons and becomes positively - charged. When the rabbit fur is rubbed on another glass rod, that glass rod also loses electrons and becomes positively - charged. Like charges repel each other according to the law of electrostatics.

Answer:

E. The rods will repel each other because they have like charges.
