111. Solving a chemistry problem

Calculate the total interaction energy (U = Ue Um) of two plates in an aqueous solution of NaCl with a concentration of 4 mmol/l, at distances between their surfaces of 5, 10, 15, 30, and 60 nm. Use the following data: ϕ = 0.03 V, Hamaker constant A* = 3.5*10-20 J, temperature 300 K, dielectric constant 77.8. Based on the data obtained, plot the dependence U=f(h).
