Why is it not possible to charge a metal rod held in hand by rubbing with cloth?
When a metal rod is held in hand, it gets grounded, which means the excess charge created on it during rubbing gets neutralized by the body's conducting properties. This prevents the accumulation of charge on the rod, making it unable to hold a charge.
Why copper rod cannot be charged?
Because Copper is a conductor and conductors do not hold electricity. The charge flows out. But, A copper rod can be charged if it is in a rubber handle. This will result in the charge staying in the rod, thus charging it.
Does rubbing a polythene rod with a duster take away positive charge from the cloth?
Rubbing a polythene rod with a duster can transfer electrons and create a charge imbalance (like triboelectric charging). If the polythene rod gains electrons during rubbing, it will become negatively charged, meaning the duster could potentially lose positive charge, but the overall charge conservation principle still applies.
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.
What happen when a glass rod is rubbed with fur?
Rubbing a glass rod with fur transfers electrons from the fur to the glass rod, giving the glass rod a negative charge. This charge separation creates an attractive force between the glass rod (negative charge) and the fur (positive charge), causing them to be attracted to each other.
If you rub a copper rod rather than a polythene rod the copper rod will not stay charged why not?
Copper is a good conductor of electricity, so when it is rubbed, any charge accumulated on its surface quickly redistributes throughout the rod and dissipates. This rapid conduction of charge prevents the copper rod from retaining a net charge like a polythene rod, which is an insulator and can hold onto excess charge more effectively.

How can a conductor be made to hold its charge?
It is not possible to make a ordinary conductor hold it's charge permanently.But you can make a ordinary conductor(e.g.,)a wire to hold charge for a short period.This is because a charge stored in a conductor leaks to the surroundings due to ionisation of air. But it is possible to charge a conductor like a copper sphere. for this the copper sphere is first connected to ground and a negatively charged ebonite rod near it.the copper sphere becomes positive as the negative charges in it flow to the ground.the sphere is disconnected from ground and the ebonite rod is taken away.now the copper sphere holds positive charge. note: it is easy to charge an ebonite rod by rubbing it with fur.
Where does the excess charge on a copper rod flow to if you don't use an insulator?
If you connect the rod with a conductor, part of the charge will flow to the conductor.

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.

What happens when you rub a lucite rod with fur?
Rubbing a lucite rod with fur causes the rod to become charged by friction. Electrons are transferred from the fur to the lucite rod, giving the rod a negative charge and the fur a positive charge. This is known as triboelectric charging.
Will rubbing a metal rod and silk produce an electrostatic charge?
Yes, rubbing a metal rod with silk can produce an electrostatic charge due to the transfer of electrons between the two materials. This friction creates a separation of charges, with the metal rod becoming positively charged and the silk becoming negatively charged.
What happens when you rub vinyl with wool cloth?
You build a charge when rubbing vinyl with a wool cloth. The wool cloth is very weak in holding electrons so when you rub it with the ebonite rod the electrons transfer onto the rod. The rod is negatively charged (assuming that the rod was neutrally charged). The wool becomes positively charged (assuming that the wool was neutrally charged)
What happen if after rubbing the glass rod with cloth and place it near a pieces of paper?
The glass rod will become charged and attract the paper due to static electricity. This is because rubbing the glass rod with cloth transfers electrons, giving the rod a negative charge. The paper, being neutral, will be attracted to the negatively charged rod.
