Question Question 7
An inflated balloon was pressed against a wall after it had been rubbed with a piece of synthetic cloth. It was found that the balloon stuck to the wall. What force might be responsible for the attraction between the balloon and the wall?
An electrostatic charge develops on the balloon after it has been rubbed with a synthetic cloth. Due to this charge the balloon sticks to the wall. The electrostatic force is responsible for the attraction between the balloon and the wall.
