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)ResponsesThe balloon’s charge became negative, and the hair’s charge became negativeThe balloon’s charge became negative, and the hair’s charge became negativeThe balloon’s charge became negative, and the hair’s charge became positiveThe balloon’s charge became negative, and the hair’s charge became positiveThe balloon’s charge became neutral, and the hair’s charge became positiveThe balloon’s charge became neutral, and the hair’s charge became positiveThe balloon’s charge became positive, and the hair’s charge became positiveThe balloon’s charge became positive, and the hair’s charge became positive

Answer 1

When the student rubs a balloon made of rubber on his hair, electrons are transferred from the hair to the balloon. This results in the balloon gaining extra electrons and becoming negatively charged, 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.
