The Political Science section typically refers to a field of study that focuses on the theory and practice of politics, government, and policy-making. It explores how political systems operate, how power and authority are distributed, and how political actors (such as politicians, parties, interest groups, and voters) interact within these systems. Political Science examines various forms of government, ideologies, and political behavior at local, national, and global levels.

**Electrostatics and Capacitance (Class 12)** Electrostatics deals with the study of stationary electric charges and the forces, fields, and potential they create. Coulomb’s law describes the force between two charges, while electric fields are defined as the force per unit charge. Capacitance refers to the ability of a capacitor to store charge. It is defined as the ratio of charge (Q) to potential difference (V), expressed as ( C = frac{Q}{V} ). The capacitance of a parallel plate capacit...

Unit and Dimension are fundamental concepts in physics. Units are standard quantities used to measure physical quantities, such as meters for length, seconds for time, and kilograms for mass. The International System of Units (SI) is the most widely used system, with seven base units: meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd). Dimensions refer to the physical nature of a quantity, expressed in terms of base units. For example, velocity has dimensi...
