Plastic rods are insulators, which means they do not allow the flow of electrons through them easily. This makes it difficult to charge them by contact or induction because the charges do not move freely on the surface of the rod. Conductive materials, on the other hand, allow charges to move more easily, enabling them to be charged by contact or induction.
What else can I help you with?
How would you use a duster to charge a plastic rod?
To charge a plastic rod using a duster, rub the duster against the plastic rod. The friction between the materials will transfer electrons from the duster to the rod, giving the rod a negative charge.
When the electroscopes foil leaves are charged and there is contact with the charged plastic rod this is an example of Charge by?
This is an example of charge by conduction. When a charged object, like the plastic rod, comes into contact with a neutral object, like the electroscope's foil leaves, the charge is transferred through direct contact, causing the leaves to become charged as well.
When a plastic rod is rubbed with a cloth the plastic rod gains what?
When a plastic rod is rubbed with a cloth, the plastic rod gains a static electric charge. This charge is due to the transfer of electrons between the rod and the cloth, creating an imbalance of positive and negative charges on the rod's surface.
When a plastic rod is rubbed with wool the wool acquires positive charge because?
When a plastic rod is rubbed with wool, electrons are transferred from the wool to the plastic rod. This leaves the wool with a net positive charge due to the loss of electrons, while the plastic rod acquires a net negative charge due to gaining these electrons.
An electroscope has been charged by induction with the help of a charged glass rod the charge on the electroscope will be?
The electroscope will acquire a charge that is opposite in sign to that of the charged glass rod. This is because during induction, the charge separation in the electroscope causes an attraction of opposite charges. The electroscope will acquire the same magnitude of charge as the glass rod, but with an opposite sign.
How would you use a duster to charge a plastic rod?
To charge a plastic rod using a duster, rub the duster against the plastic rod. The friction between the materials will transfer electrons from the duster to the rod, giving the rod a negative charge.
When the electroscopes foil leaves are charged and there is contact with the charged plastic rod this is an example of Charge by?
This is an example of charge by conduction. When a charged object, like the plastic rod, comes into contact with a neutral object, like the electroscope's foil leaves, the charge is transferred through direct contact, causing the leaves to become charged as well.
What happens when a glass rod has a positive charge?
Negetiv charge due to induction.
When a plastic rod is rubbed with a cloth the plastic rod gains what?
When a plastic rod is rubbed with a cloth, the plastic rod gains a static electric charge. This charge is due to the transfer of electrons between the rod and the cloth, creating an imbalance of positive and negative charges on the rod's surface.
When a plastic rod is rubbed with wool the wool acquires positive charge because?
When a plastic rod is rubbed with wool, electrons are transferred from the wool to the plastic rod. This leaves the wool with a net positive charge due to the loss of electrons, while the plastic rod acquires a net negative charge due to gaining these electrons.
When a metal ball is charged by induction using a negatively charged plastic rod what is the sign on the charge acquired by the ball?
There exists and answer to this problem if you state the following: After the ball has been in presence of the negatively charged rod, the metal ball is either grounded or discharged by another conductor leaving the original metal ball with a positive charge, hence the name charging by induction.
An electroscope has been charged by induction with the help of a charged glass rod the charge on the electroscope will be?
The electroscope will acquire a charge that is opposite in sign to that of the charged glass rod. This is because during induction, the charge separation in the electroscope causes an attraction of opposite charges. The electroscope will acquire the same magnitude of charge as the glass rod, but with an opposite sign.
When a plastic rod is rubbed with a woolen cloth what happens?
When a plastic rod is rubbed with a woolen cloth, electrons are transferred from the wool to the plastic due to the friction between the two materials. This transfer of electrons creates a static charge on the plastic rod, giving it a negative charge and the wool a positive charge.
if you rub a plastic rod with a dry cloth what charge is left on the cloth?
The cloth will acquire a negative charge. Rubbing the plastic rod transfers electrons from the rod to the cloth, leaving the cloth with an excess of electrons, giving it a negative charge.
If you were given a positively-charged rod to charge an object by induction what charge will the object get?
The object will get a negative charge. When a positively-charged rod is brought near the object, it polarizes the charges in the object, causing the electrons to move away from the rod, leaving the object with a net negative charge.
How do you permanently charge an electroscope without bringing it into contact with a charged rod?
You can permanently charge an electroscope by induction. Place a positively charged rod close to the electroscope without touching it. The electrons in the electroscope will be repelled to the top leaving a positive charge at the bottom. Remove the charged rod, then ground the top of the electroscope. This will transfer the excess electrons to the ground and leave the positive charge at the bottom, effectively permanently charging the electroscope.
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.
