Question

(1) Consider two point charges of magnitude q/2 separated by distance R and held in relative position by a massless rod. An identical massless rod with the same charges lies a distance R away, in the same plane, parallel, q and with centers aligned. I guess you better see the drawing! 2 By dimensional analysis, the force between these two objects must be some factor times kq2/R2, in other words: kq2 Find the factor C.
