If the electrophoretic mobility of a migrating colloidal particle is 0.5 (um/s)/(v/cm), estimate the zeta potential at 25°c if the value of the constant k, is 41. the viscosity of water at 25°c is 0.89 x 10-3n .s/m², and the relative permitivity for water is 78.54.

Acm ruler with main graduations from 1 to 10 from left to right there are 10 secondary graduations between each of the main graduations there is a line that begins. at the left end of the ruler 10 secondary graduations to the left of the “1 main graduation the right end of the line ends on the eighth secondary graduation to the right of 3 how long is the line
