3. A "colloid probe" mode is used in AFM to measure the adhesion. A sphere is attached to a tipless AFM cantilever. Which capillary force do you generate when probing hydrophilic surface with hydrophilic colloid probe of 2 microns in radius? Compare your results for relative air humidity of 90% and 30%.
