1) The distance between the left charge and the center charge =
1.50+0.35 nm = 1.85 nm
The distance between the right charge and the center charge =
1.50-0.35 nm = 1.15 nm
The force exerted on the center charge by the left charge = k(2e)(2e)/(1.85nm*1.85nm) = 9*10^9*4*1.6*1.6*10^-38/1.85*1.85*10^-18 = 2.69*10^-10 N to the right
The force exerted on the center charge by the right charge = k(2e)(2e)/(1.85nm*1.85nm) = 9*10^9*4*1.6*1.6*10^-38/1.15*1.15*10^-18 = 6.97*10^-10 N to the left
Net force = (6.97-2.69)*10^-10 N to the left = 4.27*10^-10 N to the left
2) The repulsive force exerted = k(q)(q)/(r*r) =
9*10^9*q*q/0.2*0.2 = 4.57*10^-21 N
q = 1.4*10^-16 C
excess electrons = 1.4*10^-16 C/1.6*10^-19 C = 891 electrons
