1) What is electrostatics ?
Ans: It is the branch of science which deals with the study of electric charges and force between them.
2) Definition of electric charge
Ans: It is the physical property of the matter that experience a force when it is place in electric field there are two types of electric charge.
i) Positive charge (+ve)
ii) Negative charge (-ve)
It is denoted by q and it's unit is coulomb (c)
3) Explain coulomb low of electrostatics or coulomb Inverse square low
Statement: It states that the force of attraction or repulsion between two electric charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.
4) Definition of electric field.
Ans: The space around the electric charge is called as electric field.
5) Definition of electric flux density.
Ans: The total number of electric lines of force per unit Area is called as electric flux density. and it is denoted by (D).
6) Definition of Electric field intensity.
Ans: The force Acting Per unit charge is called as electric field intensity. It is denoted by (E).
7) Definition of Electric flux.
Ans: The total number of electric lines of force is called as electric flux. And it is denoted by ψ (Psi) it unit is coulomb.
8) Definition of electric potential.
Ans: The amount of work done in bringing a unit positive charge from the boundary of infinity to a given point against electric field is called as electric potential and it is denoted by (v).
9) Definition of absolute potential (v).
Ans: The amount of work done is bringing a unit positive charge at a given point is called as absolute potential.
10) Definition of electric potential between two points.
Ans: The amount of work done is bringing a unit positive from point R to points S is called as potential difference between two points.
