Class 12 Physics — Nuclei Important Questions with Answers (Short 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.

Nuclei — नाभिक

Mass defect, binding energy per nucleon curve, and radioactivity (α β γ) plus decay law N = N0 e−λt. Half-life T½ = ln2/λ. Fission versus fusion on the BE curve. Write the equation that conserves charge and nucleon number. You are on Nuclei (Short answers), page 1 of 1 — 3 questions in this filter. Short answers are two-to-four line NCERT points — definition, reason, or a small numerical. Write in the language your school paper uses (Hindi or English) then match the hidden paragraph. These are the 2- and 3-mark stems teachers recycle. 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.
