A coil of a moving coil galvanometer has 100 turns and effective area of` 0.005 m^(2)`. It is suspended in a radial magnetic field of induction` 0.001 Wb//m^(2)`. The torque per unit twist of thr suspension fibre is `5 xx 10^(-9)Nm`/degree. What is the currebnt sectivity of the moving coil galvanometer?
