Question

e) What are the three ways of transferring charge from a charged body to an uncharged
body?​

Answer 1

Explanation:

Charging by rubbing: Charging of an object by rubbing it with another object is called charging by rubbing. ...

Charging by conduction: Charging a neutral body by bringing it in contact with a charged body is called charging by conduction.

Answer 2

Answer:

Transferring Charge An object becomes charged only when electrons are transferred from one location to another. Charges are neither created nor destroyed. This is a rule known as the law of conservation of charge. If one object gives up electrons, another object gains those electrons. There are three methods by which charges can be transferred to build up static electricity: charging by friction, by conduction, and by induction. Charging by Friction When two uncharged objects rub together, some electrons from one object can move onto the other object. The object that gains electrons becomes negatively charged, and the object that loses electrons becomes positively charged. Charging by friction is the transfer of electrons from one uncharged object to another by rubbing. In Figure 4, when the girl’s socks rub the carpet, electrons move from the carpet onto her sock. This causes an overall negative charge on the sock. Clothing that sticks together when it is taken out of the dryer is another example of charging by friction. Charging by Conduction When a charged object touches another object, electrons can be transferred between the objects. Electrons transfer from the object that has the more negative charge to the one that has the more positive charge. For example, a positively charged object will gain electrons when it touches an uncharged object. Charging by conduction is the transfer of electrons from a charged object to another object by direct contact. In Figure 4, charges are transferred from the girl’s feet to the rest of her body because of charging by conduction. Charging by Induction In charging by friction and by conduction, electrons are transferred when objects touch one another. In charging by induction, however, objects do not touch when the charges transfer. Charging by induction is the movement of electrons to one part of an object that is caused by the electric field of a second object. The electric field around the charged object attracts or repels electrons in the second object. In Figure 4, for example, the negative charges in the girl’s fingertip produce an electric field that repels the electrons on the surface of the doorknob. The electrons on the doorknob move away from the finger. This movement produces an induced positive charge on the doorknob.
