The Effect of a Solid Surface on the Properties of Certain Liquids

Electrostatic Forces of Adhesion Between Particles.

“…The contribution to the total charge density, cr 0 , added by the smaller sphere depends upon the square of the ratios of the diameters hence may be neglected for a small sphere contacting a much larger one. In the absence 9f a complete solution, an approximation to the charge acquired by the.s11:1aller sphere, valid qt t~e extremes, is given by (13) where d is the diameter of the smaller sphere and d 0 is the diameter of the larger one.…”
