Class 12 Physics — Electric Charges and Fields Important Questions with Answers (Long answers)

Class 12 Physics board still lives on NCERT derivations and numericals: Coulomb, Gauss, Kirchhoff, Biot–Savart, Faraday, LCR, lens-maker, Young, photoelectric, Bohr and a pn junction. This hub writes 150+ important items with hidden keys so a 20-question page is a mock, not a scroll. No invented date sheet — rationalized 2023–26 chapter names only.

Electric Charges and Fields — वैद्युत आवेश तथा क्षेत्र

Quantisation, Coulomb, superposition, E for a dipole, and Gauss for line, sheet, sphere. Field lines start on + and never cross. A conductor’s field inside is zero in electrostatics. Write the surface first when Gauss is the method. You are on Electric Charges and Fields (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
