Question

A student rubs a balloon made of rubber on his hair and notices that the balloon sticks to his hair afterwards. What happened to the electrical charges of both the student’s hair and the balloon?(1 point)
Responses

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

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

Answer 1

When the student rubs the balloon against his hair, electrons are transferred from the hair to the balloon. As a result, the balloon gains extra electrons, giving it a negative charge, while the hair loses electrons, resulting in a positive charge.

Therefore, the correct response is:

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