Surface Charge Distribution
JEE Main asked Surface Charge Distribution 2 times in 2 of the 108 shifts Lumi analysed, in 2022 and 2026. It belongs to Conductors in Fields, in Electrostatic Potential and Capacitance (Physics). The longest wait between two years asking it was 4 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2022 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 0 in 24 shifts · 2022: 1 in 24 shifts · 2023: 0 in 12 shifts · 2024: 0 in 18 shifts · 2025: 0 in 8 shifts · 2026: 1 in 9 shifts.

How JEE Main framed it
Assertion–reason is the usual form. Skill tested: conceptual.
- Assertion-reason on conductors in electrostatics
- Surface charge density ratio on merging drops
