Point a is on the +y-axis at y=+0.200 m and point b is on the +x-axis at x=+0.200 m. A wire in the shape of a circular arc of radius 0.200 m and centered on the origin goes from a to b and carries current I=5.00 A in the direction from a to b.
If the wire is in a uniform magnetic field B=0.800 T in the +z-direction, what are the magnitude and direction of the net force that the magnetic field exerts on the wire segment?
