The balloon’s charge became negative, and the hair’s charge became negative

The balloon’s charge became negative, and the hair’s charge became positive
The balloon’s charge became negative, and the hair’s charge became positive

The balloon’s charge became neutral, and the hair’s charge became positive

Answer 1

When a student rubs a balloon made of rubber on his hair, electrons are transferred from the hair to the balloon. This process results in the balloon gaining extra electrons, giving it a negative charge, while the hair loses electrons and becomes positively charged.

Therefore, the correct response is:

The balloon’s charge became negative, and the hair’s charge became positive.
