The r‐component of the Lorentz force (solid line), pressure force (dotted line), and tension force (dashed line) vs. radial height at a longitude of ﹩\phi =41^{\circ }﹩ at the midpoint of the trailing bipole on day 21. The vertical dash‐dotted lines denote the radial height of the QSL (﹩r=1.09﹩ R_⊙) and the axis of the flux rope (﹩r=1.28﹩ R_⊙)
