In the figure, two circular arcs have radii a = 15.0 cm and b = 11.5 cm, subtend angle 0 = 72.0°, carry current i = 0.477 A, and share th same center of curvature P. What are the (a) magnitude and (b) direction (into or out of the page) of the net magnetic field at P? The tolerance is + 1 in the 3rd significant digit.
