Three ways by which a body can be charged:

There are three primary ways by which a body can be charged: through friction, conduction, and induction.

1. Friction:
Friction charging, also known as triboelectric charging, occurs when two objects rub against each other, transferring electric charges. This process involves the movement of electrons from one object to another. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. Some examples of friction charging include rubbing a comb against hair or rubbing a balloon against clothing.

2. Conduction:
Conduction charging occurs when a charged object comes into direct contact with a neutral object, causing the transfer of electric charges. If a positively charged object touches a neutral object, some of the positive charges will move from the charged object to the neutral object, leaving the charged object with a reduced charge. The neutral object will then become positively charged. Similarly, if a negatively charged object touches a neutral object, some of the negative charges will transfer to the neutral object, resulting in a negative charge for the neutral object. This process of charge transfer through direct contact is called conduction charging.

3. Induction:
Induction charging involves the redistribution of electric charges on an object without direct contact with a charged object. It occurs due to the influence of an external charged object on the distribution of charges in a neutral or grounded object. When a charged object is brought close to a neutral object, the charges in the neutral object redistribute themselves temporarily. This redistribution creates a separation of charges, with the side of the neutral object closest to the charged object experiencing an opposite charge and the other side experiencing a charge of the same polarity. However, the neutral object does not become permanently charged. If the charged object is then removed, the charges return to their original distribution.

Summary:
In summary, a body can be charged through friction, conduction, and induction. Friction charging occurs when two objects rub against each other, transferring electrons and resulting in one object becoming positively charged and the other becoming negatively charged. Conduction charging involves the direct contact between a charged object and a neutral object, causing the transfer of charges. Induction charging occurs when a charged object influences the distribution of charges in a neutral object without direct contact, resulting in a temporary separation of charges.

Following are the three important ways by which a body can get charged ---
⇒By conduction: When an uncharged body is made in contact with a charged body, the charge flow into the non charged body and the body gets charged.

⇒By rubbing: When a body is rubbed with another body, both of them gets charged. One of the bodies acquires positive charge and the other acquires negative charge.

⇒By induction: When a charged particles or body is brought near non charged body without touching, charges are developed in the uncharged body.This method of charging a body is called charging by induction.
