A cell having an emf of 2 V and internal resistance of `0.5 Omega` is sending current through a tangent galvanometer of resistance `4.5 Omega`. If another external resistance of `95 Omega` is introducedm the deflection of the galvanometer is `45^(@)` , calculate the reduction factor fof the galvanometer?
