A long horizontal wire carries 15.0 AA of current due north.

A.What is the absolute value of the net magnetic field 21.0 cmcm due west of the wire if the Earth's field there points north but downward, 37 ∘∘ below the horizontal, and has magnitude 5.0 ×10−5T×10−5T?

B. What is the angle of the net magnetic field 21.0 cmcm due west of the wire if the Earth's field there points north but downward, 37 ∘∘ below the horizontal, and has magnitude 5.0 ×10−5T×10−5T?
