Introduction For the measurement of the extent of polarity, Pauling introduced the concept of Dipole moment. It is denoted by ‘µ’. The multiplication of positive or negative charge (q) and the distance (d) between two poles are called dipole moment. Here –µ = q × d (magnitude of charge × distance) Dipole moment is a […]

Introduction As we are familiar with the concept of an electric dipole, let us now look at the concept of torque on a dipole which is a simple topic and a scoring one. A dipole is a magnetised pole with an equal amount of positive and negative charges separated by distance (d). When a dipole is

The dimensional formula of any bodily amount is the expression that represents how and which of the bottom portions are protected in that amount. It is denoted by enclosing the symbols for base portions with suitable strength in rectangular brackets, i.e., [ ] An example is the dimension formula of mass, which is written as

The electric force was described as a noncontact force by the unit of static electricity. Actions that were performed at a distance are termed field forces. Scientists used this term to explain the phenomena of the force that occurs in the absence of physical contact. Due to the presence of any charge, the space surrounding

Electric charges are the fundamental entity in electrostatics. Like mass, it is considered to be an elementary entity of an object. We know that the constituent particles of any object have charges (electrons and protons). Charges are conserved in nature. It simply means that the total number of positive and negative charges are constant. In

Coulomb’s Law is the mathematical expression of force exerted by charged objects on one another. (Analogous to Newton’s Law of Gravity.) F = K(|q1| | q2| /r2) The symbol k in this context refers to electrical forces and has nothing to do with spring constants or Boltzmann’s constant!    K            = 

In the context of other matter containing charge, the charge is the fundamental feature of matter that exhibits electrostatic attraction or repulsion. Many subatomic particles have electric charge as a distinctive attribute. While placing a matter in an electromagnetic field, it tends to acquire an electric charge, which results in it experiencing a force. A

A dielectric is defined as a non-conducting material that does not allow the current to flow through it. The material used in these dielectric slabs does not allow the conduction of current. They are used in many electrical devices to restrict current flow. Dielectric slabs do not allow the flow of current because they do

Degenerate Orbitals are orbitals that have the same levels of energy as one another. They are related with a number of different concepts, including the Aufbau Principle, Hund’s rule, and Pauli’s Principle, all of which help us comprehend the fundamental method in which electrons are distributed throughout the various orbitals. Degenerate Orbitals are electron orbitals

By the process of friction or rubbing, conduction and induction a neutral body loses its electron and gets electrified to a charged body. Those two charged bodies influence the surroundings and create an electric field. In the presence of another charge in the electric field of a charge, the field modifies and a special type
