Equilibrium of a String Junction (Knot)
JEE Main asked Equilibrium of a String Junction (Knot) 2 times in 2 of the 108 shifts Lumi analysed, in 2022 and 2025. It belongs to Newton's Laws of Motion, in Laws of Motion (Physics). The longest wait between two years asking it was 3 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2022 and 2025. 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: 1 in 8 shifts · 2026: 0 in 9 shifts.
