A coil 2.0 cm in diameter has 300 turns. If the coil carries a current of 10 mA and lies in a magnetic field $$5 \times 10^{-2}$$ T, the maximum torque experienced by the coil is

A

$$4.7 \times 10^{-2}$$ N-m

B

$$4.7 \times 10^{-4}$$ N-m

C

$$4.7 \times 10^{-5}$$ N-m

D

$$4.7 \times 10^{-8}$$ N-m
