Q7. 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?

On rubbing the balloon against a piece of synthetic cloth the balloon gains charge. The wall is uncharged and is attracted by the charged balloon since a charged body attracts an uncharged body. The electrostatic force is responsible for the attraction between the balloon and the wall.
