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 I_(0) passes through it and produces a deflection of pi//2 of the pointer. Then answer the following questions based on the paragraph. If the charge Q is passed almost instantaneosly through the coil, the angular velocity of the coil, immediately after this is
