e plates. If rr is the electric density on i\ and S its area,Sfr will be its charge, and 27ro-S the force with which it is urged downwards,and which must be balanced by weights in the pan /. If K is this force,F = 27r/rS. This force can be measured in dynes as explained above, andfrom the result we… … Fig. 780 8i6 Frictional Electricity [797- if y, stands for the force which would be exerted upon a unit of positiveelectricity anywhere between the plates. In words, this equation is a state-ment that the difference of potentials is ecjual to the work that must be doneagainst electric force to…
