We derived the expression of potential energy in terms of the angle made by the direction of the electric dipole moment and the direction of the external uniform electric field. We found that the potential energy is the negative of the dot product of dipole moment and the electric field.
The potential energy of interaction between dipoles is given by,
V=−4πϵ0r32P1P2
Here the dipole P1 is inclined to the dipole P2 at an angle θ,since the vertical component of P1 is perpendicular to P2 is zero i.e. P1sinθ is zero, taking horizontal component of P1 along P2 i.e. P1cosθ we get
V=−4πϵ0r32P1P2cosθ
V=−r32kP1P2cosθ..........(since, k=4πϵ01)

In the science of spectroscopy, under physics, the Rydberg constant is a physical constant relating to atomic spectra. It is denoted by R∞ for heavy atoms and RH for Hydrogen. Rydberg constant was first arising from the Rydberg formula as a fitting parameter. Later Neils Bohr has calculated it from fundamental constants.

Every political party and candidate gets a fair and equal chance to compete. According to our election law, no party or candidate can:
- bribe or threaten the voters to vote for them only;
- appeal to the voters in the name of caste or religion;
- use the government resources for election campaigns;
- spend more than ?25 lakhs in a constituency for the Lok Sabha elections or ?10 lakhs in a constituency during an assembly election.
If they do so, their election can be rejected by the court even after they have been declared elected.

When the valence electrons are represented as dots circling the elements it is known as the elemental structure with electron –dot.
Thus for option i) we can write Sodium (2, 8, 1) = Na with one electron at the top. Again for Oxygen (2, 6) = O with two electrons each on three sides.
For Magnesium (2, 8, 2) = Mg with two electrons on the top.
The formation of Na20 and MgO can be written as Mg2+ + O2 (2-).
In Na2O, Na+ and O2- ions are present and in MgO, Mg2= and O2 (2- ) ions are present.

A relation R from a non-empty set A to a non-empty set B is a subset of the cartesian product set A × B. The subset is derived by describing a relationship between the first element and the second element of the ordered pairs in A × B.
The set of all first elements in a relation R is called the domain of the relation B, and the set of all second elements called images is called the range of R.

A consumer is in a state of equilibrium when he maximizes his satisfaction by spending his given income on different goods and services. Any deviation or change in the allocation of income under the given circumstance will lead to a fall in total satisfaction.
For two-commodity case: Rupee worth of marginal utility of money should be same across good X and good Y, and equal to marginal utility of money.
Condition 1 : MU(of good X)/ Price of good X = MU(OF GOOD Y)/ Price of good Y = MU(of money)
Reason: In case rupee worth of satisfaction (MU of good X/ price of good X) is greater for good X than good Y, the consumer will be prompted to buy more of good X and less of good Y. This would lead to a fall in marginal utility of good X and a rise in marginal utility of good Y. This process would continue till MU(of good X)/ Price of good X = MU(OF GOOD Y)/ Price of good Y = MU(of money) . In case rupee worth of satisfaction (MU of good y/ price of good Y) is greater for good Y than good X, the consumer will be prompted to buy more of good Y and less of good X. This would lead to a fall in marginal utility of good Y and a rise in marginal utility of good X.
Condition 2: Marginal utility of money remains constant.
Condition 3: Law of marginal utility holds good.

Word Processing refers to the act of using a computer to create, edit, save and print documents. In order to perform word processing, specialized software (known as a Word Processor) is needed. One example of a Word Processor is Microsoft Word, but other word processing applications are also widely used. A word processor is a device or computer program that provides for input, editing, formatting and output of text, often with some additional features. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.

Federalism is a system of government in which the power is divided between a central authority and various constituent units of the country. Usually, a federation has two levels of government. One is the government for the entire country that is usually responsible for a few subjects of common national interest. The others are governments at the level of provinces or states that look after much of the day-to-day administering of their state. Both these levels of governments enjoy their power independent of the other.

Petroleum is a fossil fuel that naturally occurs in the liquid form created by the decomposition of organic matter beneath the surface of the earth millions of years ago. These fossil fuels are then refined into usable substances such as petrol, kerosene etc. It is formed by the combination of hydrocarbons and other substances, mainly sulphur. When first collected in its natural form, it is termed as crude oil. This substance is generally characterized by a brownish-black colour. Although, it can also differ between red to pale yellow or even colourless. Its thickness (viscosity) varies from nearly solid tar-like consistency to low viscosity, almost like water.

Raoult’s law states that a solvent’s partial vapour pressure in a solution (or mixture) is equal or identical to the vapour pressure of the pure solvent multiplied by its mole fraction in the solution.
Mathematically, Raoult’s law equation is written as;
Psolution = ΧsolventP0solvent
Where,
Psolution = vapour pressure of the solution
Χsolvent = mole fraction of the solvent
P0solvent = vapour pressure of the pure solvent
