JEE Main 2022 Physics question
Two identical charged particles each having a mass 10 g and charge C 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 ]
Answer: (1)
Solution
In limiting equilibrium the electrostatic repulsion equals the maximum friction: . So $ =
