Question:

An inflated balloon was pressed against a wall after it has been rubbed with a piece of synthetic cloth. It was found that the balloon sticks to the wall. What force might be responsible for the attraction between the balloon and the wall?

Answer:

When an inflated balloon is rubbed with a piece of synthetic cloth, then it becomes charged. The balloon sticks to the wall because of the attractional force present between them. When a charged body attracts an charged or uncharged body towards itself then it is known as electrostatic force of attraction. Hence, the balloon sticks on the wall due to the presence of electrostatic force of attraction between the balloon and the wall.
