|
|
|
Protons transferred to the balloon when it was rubbed on metal.
|
|
|
Extra electrons on the surface of the balloon push away electrons in the wall, leaving a positively charged area.
|
|
|
The rubber in the balloon has a magnetic field that pulls on the wood in the wall.
|
|
|
Electricity in the balloon creates a magnetic field that attracts the metal in the wall.

Detailed explanation-1: -The charged balloon sticks to a wall due to electrostatic force between the charged balloon and the wall.
Detailed explanation-2: -It is due to the electrostatic force between the balloon and the wall. Opposite charges attract each other.
Detailed explanation-3: -On rubbing an inflated balloon with a piece of synthetic cloth, it becomes charged. A charged body attracts an uncharged body. When this charged balloon is pressed against a wall, it sticks to the wall. The force acting between the charged balloon and the wall is the electrostatic force.
Detailed explanation-4: -The balloon ends up with extra electrons, making it negatively charged. When the negatively charged balloon approaches a wall, the negative charges in the wall are repelled (or pushed away).
Detailed explanation-5: -The balloon is charged by rubbing it on your hair. When you put it near a neutral object (paper, Styrofoam or puffed rice cereal), the electrons in the object repel away from the balloon and the protons are attracted to the balloon. This movement of the electrons causes the neutral object to get a low positive charge.
