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. … The negatively charged balloon is then attracted and will “stick” to the object.
What charges would the balloon be attracted to?
Because electrons are negatively charged, the balloon acquires a net negative charge. The balloon’s negative charges are attracted to the positive charges in the can, and so the can rolls toward the balloon. As the balloon is pulled away from the can, the can will continue to roll toward the balloon (Figure 3).
Does a charged balloon attract salt?
Rubbing a balloon gives it a negative charge, also called static electricity. When the balloon gains enough static electricity, and it is brought near the mix of salt and pepper, the negative charge polarizes the salt and pepper.
What are balloons attracted to?
When the balloon has been rubbed enough times to gain a sufficient negative charge, it will be attracted to the wall. Although the wall should normally have a neutral charge, the charges within it can rearrange so that a positively charged area attracts the negatively charged balloon.
What does a charged balloon repel?
Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.) Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.
How a charged balloon can attract a neutral object?
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.
Which force causes a charged balloon to attract another balloon?
Electrostatic force causes a charged balloon to attract another balloon.
What part of salt is attracted to the balloon?
Salt is ionic, which means that it has a positive part and a negative part. Opposites attract, so the positive part of the salt is attracted to the now negatively charged balloon.
Why does pepper stick to a spoon?
As you rub the plastic spoon, you are giving the spoon a negative chargers through static electricity. The salt and pepper are positively charged but he pepper is lighter so it gets more strongly attracted to the negatively charged spoon!
Which component salt or pepper is attracted to the balloon by induction?
The mass of pepper grains is smaller than salt grains, so they are lighter and more likely to be attracted to the balloon at a large distance.
What types of charges attract?
These two types of electrical charges – positive and negative – are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object.
How does a balloon attract paper?
When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive. Since positive and negative attract, the paper moves toward the balloon. The negatively charged balloon attracts the paper.
What is a electrostatic attraction?
Electrostatic attraction is essentially the attraction between the positively charged nucleus of an atom and the negatively charged electrons surrounding it. The greater the positive charge of the nucleus (the more protons), the greater the effective nuclear charge.
Why does a balloon attract a can?
When you rub the balloon through your hair, invisible electrons (with a negative charge) build up on the surface of the balloon. This is called static electricity, which means “non-moving electricity” The electrons have the power to pull very light objects (with a positive charge) toward them – like the soda can.
Why does a balloon attract water?
The water is made of positive and negative charged particles. When you bring the balloon towards the water, the positive charged particles in the water will move the water towards the negatively charged balloon since positive and negative charges are attracted to each other.
Would you expect that can a would be attracted by the negatively charged balloon?
A negatively charged object would never be attracted to a – balloon. However, a + object would be attracted to a – balloon (opposites attract) and a neutral object would be attracted to a – balloon (since neutral objects are attracted to any charged object). vi.
