Why do charged balloons stick to walls?
Remember, objects with the same charge repel each other. … The wall is now more positively charged than the balloon. As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative).
Why the positively charged balloon is attracted to the neutral wall?
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.
What happens when a charged balloon is brought close to a wall?
When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall (negative charges repel other negative charges, and positive charges repel other positive charges). Therefore, that part of the wall is left repelled.
What force holds the balloon to the wall?
Gravitational Force holds the balloon on the wall.
Why does a balloon stick to the wall quizlet?
When the negatively charged balloon is brought near a wall, it induces a positive charge near the surface of the wall (the extra electrons on the balloon repel electrons near the surface of the wall). Since opposite charges attract, the balloon sticks to the wall.
What do the electrons in the wall do when the balloon comes closer Why?
What happens when the balloon is close to, but not touching the wall? The electrons in the wall repel because of the negatively charged balloon, exposing the positively charged nucleus, allowing the balloon and wall to attract each other. (Electrons repel to the back of the wall).
When a charged balloon sticks to the wall does the wall become charged by induction or conduction explain?
The charge on the balloon induces an opposite charge on the wall so the two objects attract each other. Induction.
How do you stick a balloon to the wall?
- Blow up the balloon and tie it.
- Rub the balloon quickly on your hair in a back and forth motion to generate static electricity.
- Place the balloon on a wall.
- If the balloon slides, firmly slide the balloon to the right place.
- Have fun!
Why do like charges repel?
When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced. … Therefore, like charges repel and unlike charges attract.
Why would a balloon attract to your hair without touching it?
Explanation: Hold the balloon (negatively charged) just above your head so your hair (positively charged) will be attracted to it and stand up on end. … … The negatively charged balloon repels the electrons of the can so that a positive charge is near the balloon.
