4.4) The B-field is uniform and perpendicular to the plane of the figure. The conductor has a straight segment with length L perpendicular to the plane of the figure on the right, with current opposite to B; followed by a semicircle with radius R; and finally another straight segment with length L parallel to the xaxis. Find the total F on these three segments of wire. B (out) R Q Fig. 4 Tutorial 4 Q 4.4 do . / (in)
