Charge on a =b= 2x10^(-5)
When c is touched to a, due to conservation of charge, charge on a=c=10^(-5)
Force by b on c, i.e. Fb = kbc/r²= kx2x10^(-10)/r² in the direction of a
Force by a on c, i.e. Fa = kac/r²= kx10^(-10)/r² in the direction of b
Net force on c = Fb-Fa = kx10^(-10)/r² in the direction of a.
I hope it helps :)
