Helical Motion and Pitch

JEE Main asked Helical Motion and Pitch 7 times in 7 of the 108 shifts Lumi analysed, in 2020, 2023, 2024 and 2026. It belongs to Lorentz Force, in Moving Charges and Magnetism (Physics). The longest wait between two years asking it was 3 years. In 2020 and 2023 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2023, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
