Indentical isolated conduction sphers 1 ...

Indentical isolated conduction sphers 1 and 2 have equal charges and are separated by a distance that is large compared with their diameters (Fig.a). The electrostatic force acting on spkhere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulation handle and initially neutral, is touched first to sphere 1 (Fig. b), then to sphere 2 (Fig. c), and dinally removed (Fig. d). The electrostatic force that now acts on sphere 2 has magnitude F'. What is the `(F')/(F)`?
