Spring-Mass in Circular Motion

JEE Main asked Spring-Mass in Circular Motion 5 times in 5 of the 108 shifts Lumi analysed, in 2020, 2022 and 2023. It belongs to Circular Motion, in Laws of Motion (Physics). The longest wait between two years asking it was 2 years. In 2020 and 2022 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2022 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
