Consider the settling of charged spherical particles with a zeta potential of \(50 \mathrm{mV}\) in a solution of \(0.05 \mathrm{M} \mathrm{NaCl}\). The particle density is \(2060 \mathrm{~kg} / \mathrm{m}^{3}\) and the particle holdup is 0.1 .

Calculate and plot the sedimentation electric field as a function of the particle diameter. Also calculate and plot the particle settling velocity and show that the correction to Stokes' law is negligible for this case.
