Capillary Rise (Ascent Formula)

JEE Main asked Capillary Rise (Ascent Formula) 3 times in 3 of the 108 shifts Lumi analysed, in 2020 and 2024. It belongs to Surface Tension, in Mechanical Properties of Fluids (Physics). The longest wait between two years asking it was 4 years. In 2020 it came in more than one shift of the same year.
