Springs in Parallel

JEE Main asked Springs in Parallel 5 times in 5 of the 108 shifts Lumi analysed, in 2021, 2022 and 2023. It belongs to SHM Equations, in Oscillations (Physics). The longest wait between two years asking it was 1 year. 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, 2022 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.

How JEE Main framed it

Diagram based is the usual form. Skill tested: application.
