Point a is on the - y-axis at y = -0.300 m and point b is on the +x-axis at x = +0.300 m. A wire in the shape of a circular arc of radius 0.300 m and centered on the origin goes from a to b and carries current I = 4.00 A in the direction from a to b. If the wire is in a uniform magnetic field B = 1.60 T in the +z-direction, what is the magnitude the net force that the magnetic field exerts on the wire segment
