A wire 60.0 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 25.0 mm, y = 0, and then in another straight line from x = 25.0 mm, y = 0 to x = 25.0 mm, y = 35.0 mm. The wire is in an external uniform 0.700-T magnetic field in the +z direction, and the current through the wire is 3.90 A, directed from the origin into the wire.(a) Determine the magnitude of the magnetic force exerted by the external field on the wire.(b) The wire is removed and replaced by one that runs directly from the origin to the location x = 35.0 mm, y = 50.0 mm. If the current through this wire is also 4.90 A, what is the magnitude of the magnetic force exerted by the external field on the wire measured clockwise from the positive x-axis?Express your answer with the appropriate units.
