Electric Field on Equatorial Line

JEE Main asked Electric Field on Equatorial Line 3 times in 3 of the 108 shifts Lumi analysed, in 2020, 2023 and 2024. It belongs to Electric Dipoles, in Electric Charges and Fields (Physics). The longest wait between two years asking it was 3 years.

Questions on this idea a shift, by year

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