Torque of Tension on Pulleys

JEE Main asked Torque of Tension on Pulleys 3 times in 3 of the 108 shifts Lumi analysed, in 2020, 2021 and 2022. It belongs to Torque and Equilibrium, in System of Particles and Rotational Motion (Physics). The longest wait between two years asking it was 1 year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021 and 2022. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
