Coulomb Force in Rutherford Scattering

JEE Main asked Coulomb Force in Rutherford Scattering 2 times in 2 of the 108 shifts Lumi analysed, in 2022 and 2026. It belongs to Coulomb's Law, in Atoms (Physics). The longest wait between two years asking it was 4 years.

Questions on this idea a shift, by year

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