Magnetic Effects of Current and Magnetism Part 2

A moving coil galvanometer has 100 turns and each turn has an area of 2.0cm2. The magnetic field produced by the magnet is 0.01T and the deflection in the coil is 0.05 radian when a current of 10‌mA is passed through it. The torsional constant of the suspension wire is x×10−5N−m∕rad. The value of x is_____
