Why does a comb attract pieces of paper even when it is not charged?
Nope, this does not contradict coulomb's law. The reason why the pieces of paper are neutral is that they contain equal amount of positive and negative charges and so they cancel each other out. When you bring a charged plastic comb to the pieces of paper, the charge opposite to that of the plastic comb will be brought to a part of the surface of the paper where the plastic comb is. Opposite charges attract each other, and since you're holding the comb, the pieces of paper will be attracted to the comb.
If you charge the end of a plastic comb and then put the same charge on the surface of a round metal ball what would happen to charge in each case?
When you charge the end of a plastic comb and then transfer that charge to a round metal ball, the charge on the ball quickly spreads out to the entire surface due to the conductive nature of the metal ball. The charge on the comb is transferred to the entire surface of the ball, resulting in a more evenly distributed charge across the metal ball.
Suppose you charge a pocket comb by friction and then walk around the room carrying the comb Are you producing an electric current?
Yes indeed, a current is just a moving charge. Even if the charge is on a comb, and you are physically moving the comb around the place.
If you charged the end of a comb and then put the same kind of charge on one place on the surface of a round metal ball on an insulating stand what would happen to the charge in each case?
The charge on the comb would spread out along the metal ball to reduce the overall repulsion between charges, creating an even charge distribution. The excess charge from the comb would induce an opposite charge on the side of the ball facing the comb, resulting in a neutralized overall charge on the ball.
What will happen to a piece of paper that contains positive charge if close to the comb contains the negative charge?
The positive charge on the paper will be attracted to the negatively charged comb. The paper will be pulled towards the comb due to electrostatic attraction. If the charges are strong enough, the paper may stick to the comb temporarily.
When you comb your hair with a plastic comb what will the sign be on the charge acquired by the comb?
When you comb your hair with a plastic comb, the comb will acquire a negative charge. This is because the friction between the comb and your hair causes the transfer of electrons, leading to an imbalance of negative charge on the comb.
Will a plastic comb with extra electrons have a positive charge?
No the answer is that it has an negitive charge
Would rubbing a plastic comb make it charged?
Yes, rubbing a plastic comb against certain materials, such as wool or fur, can create a static charge. This occurs as electrons are transferred between the comb and the material, resulting in the comb becoming charged.
How would you demonstrate static electricity with plastic comb dry hair pieces of paper?
To demonstrate static electricity with a plastic comb and dry hair, first rub the comb against the dry hair to create a static charge. Then, bring the charged comb close to small pieces of paper. The paper bits should be attracted to the comb due to the static charge, showcasing the effects of static electricity.
How does a plastic comb and dry hair produce electricity?
When you rub a plastic comb against dry hair, friction causes electrons to transfer from the hair to the comb, giving the comb a negative charge and the hair a positive charge. This separation of charges creates static electricity.
How does rubbing a plastic comb with a duster make it charged?
Rubbing a plastic comb with a duster transfers electrons from the duster to the comb due to friction. This process leaves the comb with extra negative charge, making it negatively charged.
Why is it difficult to demonstrate a charged plastic comb that can attract the neutral pieces of paper on humid day?
On a humid day, the moisture in the air can create a layer of water on the surface of the paper, preventing the plastic comb from effectively accumulating and transferring its charge to the paper. This interferes with the ability of the comb to attract the neutral pieces of paper.
How does a plastic comb and your hair dry produce electricity?
Rubbing the plastic comb against dry hair causes electrons to transfer from the hair to the comb, creating static electricity. The friction between the two materials generates a positive charge on the comb and a negative charge on the hair, resulting in the electricity buildup.
Why does a comb attract pieces of paper even when it is not charged?

The charge on the comb is transferred to the entire surface of the ball, resulting in a more evenly distributed charge across the metal ball.
Why is a rice grain tied to a thread is attracted to a plastic comb?
When a plastic comb is charged by rubbing it against a cloth or hair, it becomes negatively charged. The rice grain acquires a positive charge when it comes into contact with the negatively charged comb. Opposite charges attract each other, causing the rice grain to be attracted to the plastic comb.
What does a plastic comb and your dry hair have to do with electricity?
By combing your hair, you create friction in your hair which creates heat throughout your hair. If the electrons running around in your hair create a charge difference with another object you can create a shock or even a spark. The hair contains atoms which contain protons and electrons, therefore allowing for another object to shock you.
