 Here are the short answers for the important 2-mark and 3-mark questions based on the +2 Tamil Nadu State Board Physics syllabus : Lesson 1: Electrostatics Define Coulomb's Law: Coulomb’s law states that the electrostatic force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Formula: F = 1 4 π ϵ 0 q 1 q 2 r 2 F = \frac{1}{4\pi\epsilon_0} \frac{q_1 q_2}{r^2} Electric Dipole: An electric dipole consists of two equal and opposite charges separated by a small distance. Dipole Moment (p): p = q × d p = q \times d Corona Discharge (Action of Point): It is the ionization of air near a sharp conductor due to high electric field, leading to discharge. Applications of Capacitors: Energy storage in circuits Smoothing in rectifiers Tuning circuits in radios and TVs Properties of Electric Field Lines: Field lines start from positive charge and end at ne...
