Calculate the potential energy u of the interaction of

Calculate the potential energy u of the interaction of two plane-parallel plates in an aqueous electrolyte solution with a concentration c, with the value of the diffuse layer potential φ, relative permittivity εr and temperature t. In the calculation, take the Hamaker constant A * = 3.0 • 10–20 J. Calculations are made for the distances between the plates h: 2, 5, 10, 15, 25, 50 nm. Build a dependency graph
u = f (h).
