A conductor of length 0.10\text{ m} is placed in a magnetic field of 9\text{ mT} at an angle of 60^\circ to the field direction. It has a current of 2\text{ A}. Calculate the force on the conductor due to the field.

1. (A)8 \times 10^{-4}\text{ N}
2. (B)9 \times 10^{-4}\text{ N}
3. (C)1.6 \times 10^{-3}\text{ N}
4. (D)1.8 \times 10^{-3}\text{ N}

This question uses a figure or table from the paper — you'll see it when you practise.
