Field of an Infinite Non-Conducting Sheet

JEE Main asked Field of an Infinite Non-Conducting Sheet 5 times in 5 of the 108 shifts Lumi analysed, in 2020, 2022, 2024 and 2025. It belongs to Electric Field, in Electric Charges and Fields (Physics). The longest wait between two years asking it was 2 years. In 2024 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, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
