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 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.
How does static electricity bend water with a dry plastic comb?
Static electricity produced by rubbing the comb on dry hair creates a charge imbalance that attracts the water molecules in the stream of water. The water molecules are polar, so they are attracted to the charged comb and will align themselves with the electrostatic field, causing the water stream to bend towards the charged comb.
What happen when rubbing a comb and place near to a flowing water?
Rubbing a comb creates static electricity, which can attract small objects such as water droplets. When the charged comb is placed near flowing water, the static electricity can pull the water stream towards the comb due to the attractive force between the charged comb and the polar water molecules.
What are some examples of charging an object by polarization?
Rubbing a plastic comb with a cloth to create opposite charges on the comb's surface is an example of charging by polarization. Similarly, charging a metal sphere by touching it with a charged rod can polarize the charges on the sphere.

Suggest why the small peice of paper stick to the charged comb?
The small piece of paper sticks to the charged comb because of static electricity. When the comb gets charged by rubbing it against a material like fabric or fur, it gains excess electrons which create a negative charge. The negative charge on the comb attracts the positively charged protons in the paper, causing the paper to stick to the comb.
How does a charged comb induce a charge on nearby objects?
When a comb is charged by rubbing it against a material like wool, it becomes charged with either positive or negative charges. These excess charges on the comb create an electric field around it. When the charged comb is brought close to a neutral object, the charges on the comb repel or attract charges within the object, causing a redistribution of charges and inducing a charge on the object.
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 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.
What happens if you rub a comb on the jumper and hold it above some small pieces of tissue paper?
Rubbing a comb on a jumper creates static electricity which can attract the lightweight tissue paper pieces to the comb. The positively charged comb attracts the negatively charged tissue paper, causing the pieces to stick to the comb due to the imbalance of charges.
Charging by friction eg?
Charging by friction, also known as triboelectric charging, occurs when two different materials are rubbed together, causing a transfer of electrons between them. One material becomes negatively charged while the other becomes positively charged. This process is often used in everyday scenarios like rubbing a balloon on hair to create static electricity.
What kind of force can make a paper clp cling to a comb?
Static electricity is the force that can make a paper clip cling to a comb. When the comb is charged by rubbing it against hair or clothing, it can attract the neutral paper clip due to the difference in charges between the comb and the paper clip.
