In a moving coil galvanometer, two moving coils M1 and M2 have the following particulars: R1 = 5 Ω, N1 = 15, A1 = 3.6 × 10-3 m2, B1 = 0.25 T R2 = 7 Ω, N2 = 21, A2 = 1.8 × 10-3 m2, B2 = 0.50 T Assuming that the torsional constant of the springs is the same for both coils, what will be the ratio of the voltage sensitivity of M1 and M2?
