4. Find the value of the ξ potential on the quartz glass-water KCl-solution boundary, if in the process of electroosmosis: current strength J = 4 • 10 ^ -4 A; the transfer time of 1⋅10 ^ -8 m3 of the solution is 12.4 s; the specific electrical conductivity of the medium is κ = 1.8 × 10 -2 ohm-1⋅m-1; η = 10 ^ -3 Pa · s; ε = 81; ε0 = 8.85⋅10 ^ -12 F / m.
