The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.0m

The bent wire shown in the figure lies in a uniform magnetic field. Each straight section is 2.0m long and makes an angle of θ=60∘ with the x axis, and the wire carries a current of 2.0A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field is given by (i) 4.0k ̂T and (ii) 4.0l ̂ T?
