A moving coil galvanometer coil has a coil of area A number of turns N The radial magnetic field present is B the moment of inertia of the coil is I about its rotation axis The torque is applied by the magnetic field on the coil of the galvanometer when current Io passes through it and produces a deflection of T 2 of the pointer Then answer the following questions based on the paragraph Then the value of torsionl constant of the spring is
