write a short note on methods of charging a body
Answers
Answer:
A body can be charged by friction, induction and conduction.

Methods. There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another.
Answer:
Most objects are electrically neutral, which means that they have an equal number of positive and negative charges. In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction.
Charging by Friction:
The charging by friction process involves rubbing of one particle on another resulting in electrons moving from one surface to another. This method is useful for charging insulators.
Charging by Conduction:
The charging by conduction process involves touching of a charged particle to a conductive material. This way, the charges are transferred from the charged material to the conductor. This method is useful for charging conductors.
Charging By Induction:
Lastly, the induction charging is a charging method that charges an object without actually touching the object to any another charged object. The charging by induction process is where the charged particle is held near an uncharged conductive material that is grounded on a neutrally charged material. The charge flows between two objects and the uncharged conductive material develop a charge with opposite polarity.
These were the different methods of charge transfer. Here, in the article let us learn more about the method of charging by induction
