विद्युत आवेश तथा क्षेत्र — बार-बार पूछे जाने वाले प्रश्न
Last updated: 5 July 2026
Every RBSE Class 12 Physics board paper from 2013 to 2026 for Electric Charges and Fields, sorted and tagged so you know exactly which Gauss's-law, infinite-plane-sheet and electric-dipole-field questions to revise first.
Real previous-year questions with the exact RBSE board years they appeared in. 5 more high-yield questions — including infinite-straight-wire and dipole-torque derivations — are in the free PDF.
Write Gauss's law. Using this law, find the electric field due to a uniformly charged infinite plane sheet at a point near the sheet.

A quick map of the chapter before you download — so you know what the questions are testing.
If you have gone through the last decade of RBSE Class 12 Physics papers, you will notice Chapter 1 (Electric Charges and Fields) is tested every year without fail. It belongs to Unit I — Electrostatics and is drawn from a pool of 32 previous-year questions spanning 2013–2026, spread across MCQs, very short, short and long-answer sections. The topics rotate, but the question patterns stay remarkably steady.
Expect a quick 1-mark opener stating Gauss's law or a property of field lines. The 1.5-mark questions lean on electric potential and linear charge density numericals. The heavy marks sit in the 4-mark long answers, which almost always ask you to apply Gauss's law to find the electric field due to a uniformly charged infinite plane sheet — this chapter's single most repeated derivation, asked in 2013, 2019, 2022, 2024 and 2026 — or to derive the field due to an infinitely long straight charged wire.
So the smart way to revise this chapter is not to read it end to end, but to practise the questions RBSE actually repeats. The five questions above — and the ten in the free sample PDF — are taken straight from real board papers and tagged with the exact years they appeared, so you can see for yourself what the full RBSE Physics chapterwise PYQ book offers before you decide to buy it.
The RBSE syllabus sub-topics this chapter's PYQs are drawn from — useful for scoping your revision even if you're not buying the full book.
