ith a force equal to k l, 2> where k is a constant which de-r pends upon the units of force, distance, and mass. We shall assume that the units are so chosen that £=1. Consider now n particles of masses m^ m2, mg, • • •, mn lying in a plane at the points Pv P,be required to findtheir attraction… … Fig. 184 but these attractions cannot be added directly, since they arenot parallel forces. To find their resultant we will resolveeach into components along two perpendicular axes AX and ASrespectively. If we denote the angle XAPt by #,, we have asthe sum of the components along AX,…
