The coil of a moving coil galvanometer has $1000$ turns each of area $3\times {10}^{-4} {\mathrm{m}}^2$. Its suspension fibre has restoring torque of $2\times {10}^{-7} \mathrm{N} \mathrm{m}$ per degree and the radial magnetic field of induction $0.08 \mathrm{Wb} {\mathrm{m}}^{-2}$. If a current of $10 \mu \mathrm{A}$ is passed through it, then the deflection produced is
