1. Electrostatics is the subfield of electromagnetics describing an electric field caused by static (nonmoving) charges. Starting with free space, assuming a space charge density, , the relationship with the electric field, , is: (1) where is a universal constant of nature called the permittivity of free space. This relationship means that, in electrostatics, the space charge density acts like a volume source. The charge-field relationship is not enough, but Maxwell's equations imply the additional requirement that the electric field is irrotational (curl free): (2) which is the static version of Faraday's law. For an irrotational field, there exists a scalar potential, which leads to the definition of the electric potential, : (3) The vector identity: (4) is true for any sufficiently smooth scalar field for and ensures that the field is irrotational.The negative sign for the electric potential is an old convention. By combining the above, the information contained in Maxwell's equatio...

The second law of electrostatics states that the attractive or repulsive force that is exerted between two charges particles is directly proportional to the strength of their charges and inversely proportion to the square of distance between the two charges. This means that bigger the charges,...

F = k Q 1 Q 2 r 2, The proportionality constant k is called the electrostatic constant and has the value:

### What are the three laws of electric charges?

The three laws of electric charges are that like charges repel, unlike charges attract and that charged objects can be attracted to neutral objects. This means that two objects with the same charge push away from each other, while two objects with opposite charges pull towards each other.

### Why do we study electrostatic charges?

In the case of electrostatic we study the behaviour of electric charges which are not in motion. To understand the concept of a charge, think about an atom which is electrically neutral because it is composed of equal number of positive and negative charges in the form of protons and electrons respectively (neutrons are electrically neutral).
