Question

A wire 70.0 mm long is bent in a right angle such that the wire starts at the origin and goes in a straight line to x = 30.0 mm , y = 0, and then in another straight line from x = 30.0 mm , y = 0 to x = 30.0 mm , y = 40.0 mm . The wire is in an external uniform 0.700-T magnetic field in the +z direction, and the current through the wire is 4.30 A , directed from the origin into the wire.

1. Determine the direction of the magnetic force exerted by the external field on the wire measured clockwise from the positive x axis.

Values I got that were incorrect: 53.13,323.13, and 306.87

2. The wire is removed and replaced by one that runs directly from the origin to the location x = 30.0 mm ,y = 40.0 mm . If the current through this wire is also 4.30 A , what is the direction of the magnetic force exerted by the external field on the wire measured clockwise from the positive x axis.?

please explain if possible
