Electric Flux Calculation

JEE Main asked Electric Flux Calculation 6 times in 6 of the 108 shifts Lumi analysed, in 2020, 2021, 2024 and 2025. It belongs to Gauss's Law, in Electric Charges and Fields (Physics). The longest wait between two years asking it was 3 years. 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 2020, 2021, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
