- Electro means “study of charges”
- Statics means “Rest”
“The study of charges at rest under the action of electric forces is known as Electrostatics.”
Electrostatics is basically the study about the charges who are at rest and are not moving.
“It is the internal property of a material that it can attract or repel the other object is called as Charge.”
There are only two charges
Positive Charge (+)
Negative Charge (-)
“When the distance between two charges is greater than their radius, then these charges are said to be point charges.” Or
“Charges having negligible dimensions (size, length, volume etc) than the other charge is known as point charges.”
“An electric force is a force that holds the positive and negative charges that make up atoms and molecules.”
The human body is composed entirely of atoms and molecules, thus we owe our existence to the electric force.
Fundamental Laws of Electrostatics
There are three fundamental laws of electrostatic that are following:
Like charges repel each other.
Unlike charges attract each other.
