Suspended Charge Mechanics
JEE Main asked Suspended Charge Mechanics 2 times in 2 of the 108 shifts Lumi analysed, all in 2021. It belongs to Coulomb's Law, in Electric Charges and Fields (Physics). In 2021 it came in more than one shift of the same year.

Questions on this idea a shift, by year
2017–2026. Asked in 2021. 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: 2 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 0 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
