Electric Field An  Electric field  can be considered an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. Electric fields are usually caused by varying magnetic fields or electric charges. Electric field strength is measured in the SI unit volt per metre (V/m). What Is an Electric Field? An electric field is defined mathematically as a vector field that can be associated with each point in space, the force per unit charge exerted on a positive test charge at rest at that point. The formula of the electric field is given as, E  =  F  / Q Where, E is the electric field. F is the force. Q is the charge. The direction of the field is taken as the direction of the force which is exerted on the positive charge. The electric field is radially outwards from the positive charge and radially towards the negative point charge....

Coulomb's Law The Coulomb's law is a fundamental principle in physics, specifically in the study of electrostatics. It describes the force between two charged objects. According to  Coulomb’s law , the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges. In CBSE Class 12 Physics, you might be required to solve problems involving Coulomb's law, calculating forces between charged particles, determining the direction of forces, and understanding the implications of changes in charge magnitude or distance between charges. History of Coulomb’s Law In 1785, French physicist Charles Augustin de Coulomb coined a tangible relationship in mathematical form between two bodies that have been electrically charged. He published an equation for the force causing the bodies to at...

Neeraj Anand-Electric Charge-Types-Properties-Electrification-Physics Class 12 Notes Study Material-Anand Classes The Electric Charges is one of the important chapters of the Class 12th Physics. Students can easily cover the chapter with the help of the Electric Charges and Fields Class 12 notes. In the notes, all the concepts and topics are explained in a creative and precise manner. The Electric Charges Class 12 notes are considered to be important study material throughout the preparation. As it helps students to understand the chapter Electric Charges in many different ways. One of the important ways is by practising questions given in the chapter Electric Charges and Fields notes. By practising many questions students can increase their overall score in the examination by performing too well in the examination.  WHAT IS AN ELECTRIC CHARGE?   Electric charge can be defined as a fundamental property of subatomic particles that gives rise to the phenomenon of experiencing ...
