Find the force on each wire

[QUOTE="andrewkirk, post: 5440933, member: 265790"] The force lines are the lines showing the direction in which the magnetic field flows. Imagine that in the number plane the mag field (which we assume is uniform, although the question does not state that) flows in the positive y direction (ie up). Then the statement 'extremities A and C are in the same force line' means that A and C have the same y coordinate. The trouble is that the problem is not fully specified, because we do not know the relative lengths of AD and DC. If they are the same then the triangle ADC will be equilateral and the forces on the two wires will be of equal magnitude but opposite direction. If the lengths are not the same then the triangle will not be equilateral, the angles the wires make with the force lines will be different, and the magnitude of the forces will be different.
