Potential Energy Curves and Equilibrium

JEE Main asked Potential Energy Curves and Equilibrium 2 times in 2 of the 108 shifts Lumi analysed, in 2021 and 2022. It belongs to Work and Kinetic Energy, in Work, Energy and Power (Physics). The longest wait between two years asking it was 1 year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021 and 2022. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
