Electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.

Explanation:

Sweater is a conductive material, which means it readily gives away its electrons. Consequently, when you rub a balloon on Sweater, this causes the electrons to move from the Sweater to the balloon's surface. The rubbed part of the balloon now acquired a negative charge. Objects made of rubber, such as the balloon, are basically electrical insulators, meaning that they resist electric charges flowing through them. This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral after electrostatic process.
