A straight wire of length $0 \cdot 5 \mathrm{~m}$ and carrying current of $1 \cdot 2 \mathrm{~A}$ is placed in a uniform magnetic field of induction $2 \mathrm{~T}$. The magnetic field is perpendicular to the length of the wire. What is the force acting on the wire? $\left[\sin 90^{\circ}=1\right]$
