JEE Main 2022 — Electrostatics Question with Solution
From: JEE Main 2022 (Online) 24th June Evening Shift
Question
Two identical charged particles each having a mass 10 g and charge 2.0 107C are placed on a horizontal table with a separation of L between them such that they stay in limited equilibrium. If the coefficient of friction between each particle and the table is 0.25, find the value of L. [Use g = 10 ms2]
