A coil is 30 turns of wire, each of area 10 cm2 , is placed with its plane at right angles to a magnetic field of 0.1 T. When the coil is suddenly withdrawn from the field, a galvanometer in series with the coil indicates that 10^(-5) C passes around the circuit. What is the combined resistance of the coil and the galvanometer?
