    Graduate J.J Thomson's determination of of the ratio m/e

    In Thomson's experimental determination of the ratio m/e of the mass to the charge of an electron, in which the electrons were subjected to an electric field of intensity E and a magnetic field of intensity H, the equations m[d2x/dt2) + He(dy/dt) , m[d2y/dt2) - He(dx/dt) = 0 , were...
