Two identical charged particles each having a mass $\displaystyle 10$ g and charge $\displaystyle 2.0 \times 10^{-7} C$ are placed on a horizontal table with a separation of $\displaystyle L$ between them such that they stay in limited equilibrium. If the coefficient of friction between each particle and the table is $\displaystyle 0.25$ , find the value of L . [Use $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ ]
