If you rub a polythene rod with a woolen cloth, electrons are transferred from wool towards the surface of the polythene rod . While the dry cloth gains the electrons lost from the the perspex rod. This means that the dry cloth has more negative charges than positive charges and so it becomes negatively charged.
What happens when you rub a plastic rod?
For example, when a plastic rod is rubbed with a duster, electrons are transferred from one material to the other . The material that gains electrons becomes negatively charged. ... The duster picks up electrons from the rod. This leaves the rod with a positive overall charge and the duster with a negative overall charge.
What happens when you rub 2 objects together?
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material . This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
When you rub a plastic rod with fur The plastic rod becomes negatively charged?
When you rub a plastic rod with fur, the plastic rod becomes negatively charged and the fur becomes positively charged. As a consequence of rubbing the rod with the fur, the rod gains mass and the fur loses mass. the electric force between charged particles decreases with increasing distance.
When 2 plastics rods are rubbed with fur then brought close to one another what will happen?
Rubbing the rods with a cloth cause them to acquire the same charges. Since like charges repel each other, the two rods will repel each other .
How does a plastic rod get charged by rubbing it?
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.
What objects are attracted to a plastic rod rubbed with wool?
A (charged) plastic rod rubbed with wool attracts small pieces of paper .
Do 2 neutral objects attract?
Any charged object – whether positively charged or negatively charged – will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other ; and negatively charged objects and neutral objects attract each other.
Do all objects get charged by rubbing?
Answer: No,all objects does not gets charged by rubbing . Since rubbing is the process in which one body transferred its own charge to other body but the required condition is that both the body posses a property known as electro-static(Charge at rest).
When two like charges are brought together they will?
Like charges repel each other ; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
When you rub a plastic rod against your hair several times?
Answer: a) both get opposite charge . Explanation: When you rub plastic with your hair it get charge through process of conduction ,and when you put near some bits of paper the paper get opposite charge through induction.
What happens when you rub a glass rod with silk?
When you rub the glass rod with the silk, the rod charges positive . If you place a charged rod on one of the swivel stands, and then bring another charged rod close to it, you can show electrostatic repulsion (similarly charged rods) or electrostatic attraction (oppositely charged rods).
When wool and plastic are rubbed together the plastic becomes?
| A B | When a plastic rod is rubbed with wool, the wool acquires a positive charge because electrons are transferred from the wool to the rod. | How is a positive charge usually given to a neutral object? electrons are removed from the object. |

What happens when a positively charged rod is brought near a plastic ball?
Protons are never transferred in electrostatic activities. In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively. ... It is touched by a positively charged metal rod. As a result, the metal sphere becomes charged positively.
Does plastic have a positive or negative charge?
Since the plastic has more electrons than protons, it has a negative charge . Since their fingers gave up some electrons, their skin now has more protons than electrons so it has a positive charge. The positive skin and the negative plastic attract each other because positive and negative attract.
What happens when you rub a metal rod with a cloth?
Dissimilar objects have different affinities for electrons. When two such objects, initially neutral, are rubbed together, the friction may cause electrons to pass from one to the other. ... Rubbing a metal rod with a wool cloth can also transfer electrons .
