A moving coil galvanometer has 50 turns and each turn has an area `2xx10^(-4)m^(2)` . The magnetic field produced by the magnet inside the galvanometer is 0.02T. The torsional constant of the suspension wire is `10^(-4)nm rad^(-1)`. When a current flow through the galvanometer, a full-scale deflection occurs if the coil rotates by 0.2 rad. The resistance of the coil of the galvanometer is `50 Omega`. This galvanometer is to be converted into an ammeter cable of measuring current in the range `0-1.0A`. For this purpose, a shunt resistance is to be added in parallel to the galvanometer. The value of this shunt resistance, in ohms, is find n ____________.
