Cylindrical Field

JEE Main asked Cylindrical Field 5 times in 5 of the 108 shifts Lumi analysed, in 2022, 2023 and 2024. It belongs to Gauss's Law, in Electric Charges and Fields (Physics). The longest wait between two years asking it was 1 year. In 2022 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2022, 2023 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.

How JEE Main framed it

Numerical value is the usual form. Skill tested: multi-step.

  • Time period of charge orbiting line charge
  • Graph of kinetic energy of orbiting charge vs radius
