Two moving coil galvanometers A and B having identical springs are placed in magnetic fields of 0.25 T and 0.5 T respectively. If the number of turns in A and B are repsectively 36 and 48, and the areas of the coils A and B are 2.4 10⁻³ ~m ^2 and 4.8 10⁻³ ~m ^2 respectively, then the ratio of the current sensitivities of the galvanometers A and B is
