Two identical charged particles each having a mass 10 g and charge `2.0 xx 10^(-7)` 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 ms^(-2)`)

A

12 cm

B

10 cm

C
