Work Done in Field

JEE Main asked Work Done in Field 4 times in 4 of the 108 shifts Lumi analysed, in 2020, 2021 and 2025. It belongs to Electric Potential, in Electrostatic Potential and Capacitance (Physics). The longest wait between two years asking it was 4 years. In 2021 it came in more than one shift of the same year.
