Question

In the figure, point P is at perpendicular distance R = 2.31 cm from a very long straight wire carrying a current. The magnetic field B set
up at point P is due to contributions from all the identical current-length elements ids along the wire. What is the distances to the
element making (a) the greatest contribution to field B and (b)10.4% of the greatest contribution?
