Error Analysis in Searle's Experiment

JEE Main asked Error Analysis in Searle's Experiment 4 times in 4 of the 108 shifts Lumi analysed, in 2021, 2022, 2024 and 2026. It belongs to Elasticity, in Units and Measurements (Physics). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
