Given Mass m=5gCharge q=10 CDistance d= 10cmThe electric force on one of the particles due to the other is
F= 1/4π∈*q²/d²
The frictional force in limiting equilibrium
f=umg
As these two forces balance each other,
umg=1/4π∈*q²/d²
u=1/4π∈*q²/mgd²
Using the above formula and substituting the values you can find out coefficient of limiting friction.
