Answer :
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.
Electrons could move from the sweater to the balloon making the sweater positively charged and the balloon negatively charged.
One of the ways of producing charges is by friction. When one object is rubbed against another, electrons are transferred from one object to the other. One object becomes positively charged while the other object becomes negatively charged.
It is possible that when the sweater is rubbed against the balloon, electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.
