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.
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.
Which material get easily charged by rubbing and what such material is called?
An insulator Becomes statically charged when rubbed against another insulator
After rubbing a plastic rod with a woolen clothmark noticed that the rubbed plastic rod picked up saw dust.explain what happened?
Rubbing the plastic rod with a woolen cloth transferred electrons from the wool to the plastic, giving the plastic a negative charge. The saw dust, being positively charged, was attracted to the negatively charged plastic rod due to electrostatic forces, causing it to stick to the rod.
Why does rubbing wool against plastic create static electricity?
Rubbing wool against plastic doesn't actually "create" static electricity. However, rubbing wool and plastic together does increase the surface area of the two materials that are coming into contact. When this happens electrons are exchanged between the two surfaces creating an imbalance. It is this imbalance of electrons that we see as static electricity.
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.
Does rubbing alcohol damage plastic?
Yes, if the plastic is left in it for long periods of time it will dry rot the plastic when it is removed from the rubbing alcohol.
Does rubbing alcohol melt plastic?
Depends on the type of plastic.
What charge develops on rubbing plastic straw with polythene?
When you rub a plastic straw with polythene, the plastic straw becomes negatively charged due to the transfer of electrons between the materials. Electrons are transferred from the polythene to the plastic straw, leaving the straw with a negative charge.
Why do the cloth and plastic rod become charged when rubbing with each other?
When you rub the cloth and plastic rod together, friction causes the transfer of electrons between the two materials. This transfer of electrons leads to one material becoming positively charged (due to losing electrons) and the other becoming negatively charged (due to gaining electrons). This imbalance of charges results in both materials becoming charged.
What happens when a plastic rod is rubbed with a Peace of fur?
Rubbing a plastic rod with a piece of fur causes the transfer of electrons between the two materials. The plastic rod becomes charged negatively, while the fur becomes positively charged. This is known as triboelectric charging.
Why does a charged glass rod attract charged plastic straw?
it is becuase when a glas rod charged by rubbing a cloth it aquires positive charge and when a plastic straw is charged by rubbing a cloth it aquires negative charge. Therefore a charged glass rod attracts a charged plastic rod.
