(Answered) A long horizontal wire carries 260a of current due north

Academics

A long horizontal wire carries 26.0A of current due north. The Earth's field 22.0cm due west of the wire points north but downward, 47° below the horizontal, and has magnitude of 5.0×10-5T.

a) What is the magnitude of the net magnetic field 22.0cm due west of the wire?

b) What is the angle below the horizontal of the net magnetic field 22.0cm due west of the wire?
