Question

What is the significance of the electric field?

Answer 1

Hint: In this question use the definition of electric field which states that it is the region around a charged particle or object within which another charged particle will experience a force over it, this force can be either a force of attraction or a force of repulsion.

Complete Step-by-Step solution:
Physical significance of an electrical field:
An electric field always surrounds an electric charge, and exerts force on other charges in the field, attracting or repelling them.
Electric fields are created by electric charges or by time-varying magnetic fields, both are the demonstration of electromotive force (EMF).
Since force is a vector quantity so electric field is a vector quantity.
The electric field at any point in the space around the system of charges will feel the force (Whether it is repelling or attracting) if a unit positive test charge is placed at that point, the term field which is defined at every point in space, may vary from point to point.
So this is the required answer.

Note – Another way to see the significance of electric field is that electric field is an elegant way of characterizing the electrical environment of a system of charges. System of charges because a single charge can’t be used to define an electric field. A system of charge can also include more than two charges too.
