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.

What type of charge does plastic collect when rubbed?
Plastic typically becomes negatively charged when rubbed, meaning it gains excess electrons. This can cause the plastic to attract positively charged objects or repel other negatively charged objects.
Is plastic positively or negatively charged?
Plastic is typically electrically neutral, meaning it has an equal number of positive and negative charges. However, it can become positively or negatively charged through a process called static electricity, where electrons transfer between objects, causing an imbalance of charges.
Is plastic a ionic compound or molecular compound?
Plastic is a molecular compound because it is comprised of long chains of molecules called polymers, which are made up of repeating units of smaller molecules. Ionic compounds are made up of positively and negatively charged ions held together by electrostatic forces.
Why does plastic stick to your hand?
It's because of Static electricity Human skin is easily positively charged. Plastic wrap is an insulator which means it does not allow electrons to flow from one to the other. Plastic wrap is negatively charged and human skin is positively charged and opposite charges attract. They are forever attracted to each other because human can earth electrons (which means making materials all neutral, equal number of protons and electrons) if the electrons are transffered from a conductor (which allows electrons to move freely from one to the other). e.g aluminium foil. Aluminium foil is a conductor which allows electrons to move freely from one to the other and electrons are transferred to positively charged hands and human earths it, so human is neutral overall and the aluminium foil is positively charged overall. e.g) plastic wrap is an insualtor which does not allow electrons to move freely from one to the other. and electrons are attracted to positively charged hands so therefore, they cling. And because it's an insulator, it will never ever let electrons transfer to human hands! So they will forever repeat :) Hope this helps. Cheers
Which material get easily charged by rubbing and what such material is called?
An insulator Becomes statically charged when rubbed against another insulator
What type of charge does plastic collect when rubbed?
Plastic typically becomes negatively charged when rubbed, meaning it gains excess electrons. This can cause the plastic to attract positively charged objects or repel other negatively charged objects.
Is plastic wrap a positive or a negative?
It is a negatively charged object
Why does a ping-pong ball attract then repel on a plastic rod?
A ping-pong ball attracts to a plastic rod due to static electricity. When the plastic rod is rubbed with a cloth, it becomes negatively charged, while the ping-pong ball can become positively charged through contact or induction. The attraction occurs because opposite charges attract. Once the ball is close enough, it can become negatively charged as well, leading to repulsion since like charges repel each other.
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.
Is plastic positively or negatively charged?
Plastic is typically electrically neutral, meaning it has an equal number of positive and negative charges. However, it can become positively or negatively charged through a process called static electricity, where electrons transfer between objects, causing an imbalance of charges.
What happens if plastic rod is rubbed with silk cloth?
When a plastic rod is rubbed with a silk cloth, electrons are transferred from the silk to the plastic rod. This results in the plastic rod becoming negatively charged and the silk cloth becoming positively charged. This effect is known as triboelectric charging.
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 does water attract to a charged plastic rod?
Water is a polar molecule, meaning it has a positively charged side and a negatively charged side. When a charged plastic rod is brought near water, the positive or negative charges on the rod interact with the corresponding charges on the water molecules, causing the water to be attracted to the rod.
Why you can not charge plastic rod by contact or induction?
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.
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.
What will happen if a negatively charged rod is brought close to a small plastic ball if the ball is postively charged?
They will attract becuase oppsites attract. If something is positivley charge and the other this is negativley charged they will almost always attract. Hope I helped.
What happens to a balloon rubbed with plastic wrap and why?
When a balloon is rubbed with plastic wrap, the balloon becomes negatively charged due to the transfer of electrons from the plastic wrap to the balloon. This results in the balloon being attracted to positively charged objects or surfaces, due to the attraction between opposite charges.
