[email protected]®© A student measures a particle response ina microelectrophoresis experiment. Theelectrical ﬁeld was created using anapplied voltage of 48 V over a distance of8.7 cm. The particle was observed tomove towards the positive electrode. Ittook 13.4 s to move a distance of 0.14mm. Calculate the electrophoretic mobility.Hint: to make it easier, convert alldistances to metres. Give your answer inm2 V‘1 3’1. Enter your answer in the format#.##E-# where each # represents a digitfrom 0-9 *Don’t forget to include the sign of themobility. Answer: < > G <1 ‘lLD’l‘
