What happens when a charged Perspex is brought near another charged Perspex?

If two negatively charged objects are brought close together, then they will repel each other. If two positively charged objects are brought close together, then they will repel each other. If a positively charged object is brought near to a negatively charged object, they will attract each other.

Are Perspex and polythene conductors or insulators?

They allow electric charges to move through them. Materials such as wood, glass and polythene are insulators. They do not allow electric charges to pass through them.

What happens when the oppositely charged objects are brought close to each other?

Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other.

What type of charge does acrylic plastic and polythene produce?

All the objects made of clear plastic called acrylic plastic get positive charge on rubbing. All the objects made of polythene plastic gets negative electric charge on rubbing. 3) When we rub a plastic comb in dry hair, then both, the comb and hair get charged but with opposite charges.

What is polythene and perspex?

As nouns the difference between polythene and perspex is that polythene is (organic compound|chiefly|british) a light thermoplastic used in packaging etc; polyethylene while perspex is (british|nz) any tough, transparent plastic that is used instead of glass for windows.

What happens when the polythene is being charged?

When a piece of polythene is rubbed with a cloth, it becomes charged. Electrons are ‘rubbed’ off the cloth and onto the polythene by friction. This makes the polythene negatively charged and leaves the cloth positively charged.

Is polythene positively charged?

What are perspex and polythene?

How is the force between two charges affected when each charge is doubled and distance between them is also doubled?

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.

What is the charge of polythene?

How does polythene become charged when rubbed?

When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge. The duster has lost electrons, giving it a positive charge.
