have opposite electrical charges.
The most likely reason the comb is able to repel the balloon is that the balloon has a negative charge from being rubbed against the student's hair, while the comb has a neutral or positive charge. Opposite charges attract each other, so the negative charge of the balloon would cause it to be repelled by the comb.
