Orbital Time Period

JEE Main asked Orbital Time Period 10 times in 10 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023, 2024 and 2026. It belongs to Orbital Mechanics, in Gravitation (Physics). The longest wait between two years asking it was 2 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, 2022, 2023, 2024 and 2026. 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

Single correct is the usual form. Skill tested: calculation.

  • Period ratio from mass and radius
  • Orbital period scaling in non-uniform mass distribution
