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 synthetic cloth it becomes electrically charged.
This electrically charged balloon attracts the wall (which is an uncharged body)
This attraction of charged balloon towards uncharged wall is known as electrostatic force.
