The net charge in a current carrying wire is zero still magnetic field exerts a force on it, because a magnetic field exerts force on

A wire is bent in the form of an equilateral triangle of side $100 \mathrm{cm}$ and carries a current of $2 A.$ It is placed in a magnetic field of induction $2.0 T$ directed perpendicular into the plane of paper. The direction and magnitude of magnetic force acting on each side of the triangle will be
