Now take that same balloon and drag it over to the wall. You will notice that the blue negative charges move away in the wall and then the balloon sticks to the wall. This charge distribution is called induction, because the negative charges move without any touching. Why does the balloon stick to the wall?
The balloon sticks to the wall because of the electrostatic forces between the negatively charged balloon and the positively charged wall. When the negatively charged balloon is brought close to the neutral wall, the negative charges in the balloon repel the electrons in the wall, causing them to move away from the balloon and accumulate on the opposite side of the wall. This redistribution of charges creates an uneven distribution of positive and negative charges on the wall.
The positive charges on the wall are attracted to the negatively charged balloon, resulting in an electrostatic force of attraction between the two. This force causes the balloon to stick to the wall. The attraction is strong enough to overcome the gravitational force acting on the balloon, allowing it to stay attached to the wall.
