Question

The branch of physics which deals with the properties of electrified bodies due to a moving charge is called electrostatics. True / False?

Answer 1

Hint: Electrostatics is a name consisting of two words, namely “electro” and “statics”. Electro means electric, hence referring to the electric charges we will study under this branch. Static stands for stationary. So using this understanding, decide whether the given statement is true or false.

Complete step by step answer:
Electrostatics is the branch of physics that deals with electric charges which are described by Coulombs and the associated forces with them. The term electrostatic comprises two words which are “electro” and “static”. Electro stands for the electric charges we deal with within this field of study. Static means stationary i.e. at rest. Thus, it means that the electric charges studied under this branch are at rest.
The branch of physics which studies and deals with the electric charges under motion and thus resulting in phenomena like an electric current, magnetism, etc. is known as electrodynamics.
The given statement “The branch of physics which deals with the properties of electrified bodies due to moving charge is called electrostatics”, is thus clearly wrong as it is confusing between two different definitions and their associated terms.

Therefore, the given statement is False.

Note:
The practical application of electrostatics can be seen in applications like photocopiers, inkjet printers, laser printers, smoke precipitators, and electrostatic air cleaning and in research instruments like Van de Graff. Similarly, the practical application of electrodynamics can be observed as electromagnetism in cell phones, TVs, data storage devices, speakers, microphones, MRI scanners, video and audio tapes, etc.
