A moving coil galvanometer has a rectangular wire coil of enclosed area \(0.001 \mathrm{~m}^2\) and 500 turns. The coil operates in a radial magnetic field of \(0.2 \mathrm{~T}\) and carries a current of \(6 \pi \times 10^{-8} \mathrm{~A}\). If the torsional spring constant is \(6 \times 10^{-7} \mathrm{~N}-\mathrm{m} / \mathrm{rad}\), then the angular deflection of the coil in radians is
