The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … If two objects have different charges, they attract (or pull towards) each other.
Why is hair attracted to comb on a hot day?
When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.
Why does the hair stand up on your head when you comb it?
When your hair is dry, especially after washing it and using a hair dryer, the various strands of hair may stick up and spread apart when you try to comb it. The reason is because the dry hair tends to collect positive (+) electrical charges when combed with a plastic comb.
What has happened to the comb to make it attract the hairs?
This happens because when comb is rubbed with hair there occurs a transfer of electrons from hair to the comb. Thus the comb gets negatively charged,when the charged comb is brought near the bits of paper it attracts the positive part of it.
Why do you think comb attracts some of your hair strands and papers?
Basically, when an electrification takes place, electrons are not created but they are transferred….. in the case of comb attracting tiny tiny bits of papers when rubbed with dry hair is because electrons from the dry hair gets transferred to the comb and now the comb induces a dipole in the bitties of paper and the …
Is combing your hair friction?
The comb has become charged by friction, acquiring an excess of electrons. … This leaves a net positive charge on the side close to the comb, and since unlike charges attract, the paper is attracted to the comb.
What is the charge of your hair if you comb your hair and the comb become positively charged?
The material that gains electrons becomes negatively charged while the material losing electrons becomes positively charged. The comb is positively charged implying the hair should be negatively charged. If you comb your hair and the comb becomes positively charged, then your hair becomes negatively charged.
Why does your hair stand up when you go down a plastic slide?
So you’ve gone flying down a slide and your hair stands straight up. This is because of the friction effect of sliding. It has caused a positive charge on each piece of hair. As each hair has the same charge, they all try and push away from each other, causing that funny straight hair to stand right up!
What is hair coarse?
When it comes to hair, stylists and dermatologists typically define coarse hair as having a thicker circumference than other hair types. It doesn’t mean that your hair is rough textured or hard to manage. When you take a strand of coarse hair and roll it between your fingers, you can feel its thickness.
What happens when you rubbed the balloon on your hair?
Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. … Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.
What happens when you comb your hair with a plastic comb?
If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … Shocks come from gaining or losing electric charge in a hurry.
Why do you think comb needed to be run through someone’s hair before it would affect the water?
The comb attracts the stream of water in the same way. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.
Why is my hair attracted to my hairbrush?
Electrons move from the brush to your hair or vice versa. Now one object has a positive charge and the other negative. This means they’re attracted to each other. This is why your hair moves when you bring the brush near your head.
What happens when a comb rubbed against hair and is brought near the small pieces of paper?
Your hair must become positively charged in order to repel a negative charge. … If you bring a charged comb near tiny pieces of paper, the pieces will first be attracted to the comb, but after touching they will fly away.
Why would a balloon attract your hair without touching it?
Because electrons are negatively charged, the balloon acquires a negative charge, while the hair, with its loss of negative charges, now has a net positive charge. So the balloon and hair have opposite charges, and opposite charges attract each other. That’s why the hair gets pulled toward the balloon (Figure 2).
