\mathbf B = 0.30\,\hat{i} + 0.40\,\hat{j}\,\text{T}

. A straight wire segment of length

0.20\,\text{m}

carries a

5.0\,\text{A}

current in the direction of the unit vector

\mathbf d = 0.00\,\hat{i} + 0.60\,\hat{j} + 0.80\,\hat{k}

. What is the magnitude of the magnetic force on the wire segment? a)

0.50\,\text{N}

0.24\,\text{N}

0.44\,\text{N}

0.88\,\text{N}
