10. Three long, straight wires are mounted on the vertices of an equilateral triangle as shown in the figure. The wires carry currents of \( I_{1}=5.50 \mathrm{~A}_{1} I_{2}=6.00 \mathrm{~A} \), and \( I_{3}=5.50 \mathrm{~A} \). Each side of the triangle has a length of \( 28.0 \mathrm{~cm} \), and the point \( (A) \) is located half way between \( \left(I_{1}\right) \) and \( \left(I_{2}\right) \) along one of the sides. Find the magnitude of the magnetic field at point (A)
