A copper voltameter is connected in series with a tangent galvanometer of 10 turns and 5cm in radius. Calculate the weight of copper is deposited in 30 minutes if the deflection of the galvanometer is `60^(@)`. (Horizontal component of earth's field `=28A m^(-1)and "E.C.E of copper" =32.8 xx 10^(-8)kgC^(-1)`.
