Question

Electric charges which are under the action of electric forces are known as
A) Electrostatic
B) Electric flux
C) Electric field
D) Electric field lines

Answer 1

Hint: To solve this question we have to know the definition of given options, we can simply define electrostatics, it is the study of electromagnetic phenomena that occur when there are no moving charges because the electric force is extremely strong.

Complete solution:
We can discuss through the options:

Electrostatic occurs when the charges are under the action of electric forces.

Electric flux can be defined as It is the measure of field lines through a given area.

The electric field is simply defined as the defined force per unit charge.

And last option is electric field lines; it is defined as it measures the nature of charges field lines are outward formed positive charges and inner-ward for negative charges.

As per the definitions, option A is the correct answer.

Additional information:
Actually, at equilibrium under electrostatic conditions, the electric field is zero at any point within a conducting material.
In simple words, we can define electric flux as the rate of flow of the electric field through a given area. And electric flux is proportional to the number of electric field lines going through a virtual surface. In other words, we can say the total number of electric field lines passing a given area in a unit of time.
We know some characteristics of electric field lines. The number of field lines depends on the charge. These field lines should never crossover, and electric field lines are tangent at the point where they pass through.

Note:
In classical physics, electrostatics is The electrostatic defined as it is a branch of physics that studies electric charges at rest. Electrostatic force also called coulomb force, coulomb's law deals with the force that acts between distinct electric charges. Means coulomb's law that is applied to static charges.
