A tangent galvanometer of 50 turns 8 cm mean radius, is connected in series with a silver voltameter and a battery. If the galvanometer shows a steady deflection of `45^(@)` and 0.185 g of silver is deposited in 30 minute, find the horizontal component of the earth's magnetic field (E.C.E. of silver = 0.001118 g/coulomb).
