How does a plastic comb attract paper?
You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb.
Why does a comb attract paper bits?
Initially the comb is electrically neutral. So it has no effect on the tiny pieces of paper. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.
Which type of comb is best for hair?
Use a wide tooth comb or a brush with wide-set, thin and natural bristles set in a rubber cushion for increased flexibility. They can help you gently remove snarls and detangle without yanking on your roots. Use the right brush for dry hair. A pure boar-bristle brush is the gold standard if you have dry hair.
Why does a plastic comb?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.
Can you lift the bits of paper with the plastic comb Why?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper.
What happens when a plastic comb is rubbed with hair?
Likewise, the ‘positive charge’ occurs as the result of the loss of electrons. The plastic rod being rubbed with fur is very much like the plastic comb you asked about. Like the rod with fur, when the comb is pulled through hair, it acquires a negative charge.
Is the hair in front of the comb a conductor?
Our hairs are definitely not made of plastic and now you can try this to check wheater your hair is an insulator or conductor So in front of comb, hair is an conductor.. So on conductor there are presence of free electrons that’s y it’s resistance is less than comb so w… Loading…
Why does your hair have a negative charge?
This makes your hair postive (lost electrons), the comb negative (gained electrons) and anything near the comb will be attracted if it is positive (lacking electrons relative to the comb), like water. Another example is when you rub socks on carpet.
Why is hair a conductor of static electricity?
So in front of comb, hair is an conductor.. So on conductor there are presence of free electrons that’s y it’s resistance is less than comb so while rubbing unwanted electrons of hair goes in comb so hair gets positively charged…. I hope you understood….
Likewise, the ‘positive charge’ occurs as the result of the loss of electrons. The plastic rod being rubbed with fur is very much like the plastic comb you asked about. Like the rod with fur, when the comb is pulled through hair, it acquires a negative charge.
How is a comb expected to acquire a negative charge?
The comb is expected to acquire a negative charge, like the case of rubbing a plastic rod with fur. Describe how Benjamin Franklin’s single-fluid model can explain what happens when we charge a glass rod by rub- bing it with a nylon cloth. How do we get two types of charge from a single fluid?
Why does a rod with fur have a positive charge?
Likewise, the ‘positive charge’ occurs as the result of the loss of electrons. The plastic rod being rubbed with fur is very much like the plastic comb you asked about. Like the rod with fur, when the comb is pulled through hair, it acquires a negative charge. That is, it picks up more electrons than it had before.
What happens to electrons when you comb your hair?
When you comb hair or perform another similar activity, the extra electrons that are just sitting in your hair are transferred to the brush/comb. This makes your hair postive (lost electrons), the comb negative (gained electrons) and anything near the comb will be attracted if it is positive (lacking electrons relative to the comb), like water.
