Why is the balloon attracted to the wall if it’s close by but repelled when far away?
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.
What force holds the balloon to the wall?
Gravitational Force holds the balloon on the wall.
What makes the balloon more attractive compared to it being less attractive?
Objects made of rubber, such as the balloon, are electrical insulators, meaning that they resist electric charges flowing through them. … When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall.
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.
What happens when an inflated balloon?
Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.
Why hairs are attracted towards balloon which type of force is apply here?
1: Rubbing a balloon on hair transfers negative electrons from the hair to the balloon. As the balloon is removed, it pulls on the hair with an attractive electric force. Some common materials in the triboelectric series. Fig.
What do you think will happen when the balloon is moved closer to the wall?
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). This leaves a positive charge on the wallboard at the spot where the balloon touches.
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.
Why didn’t the two balloons get attracted to each other?
The more charge something has, the more it attracts or repels. Also, the closer two charges are to each other, the greater the attraction or repulsion between them. … The balloons will repel each other – the two negative charges push each other away.
Why do particles attract each other?
Answer: By an intermolecular force known as the intermolecular force of attraction, particles of matter are attracted to one another. In the three states of matter, the intermolecular force of attraction varies.
Can a charged body attract a neutral body?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
