Chapter 28, Problem 088 In the figure below, the two ends of a U-shaped wire of mass m = 13.0 g and length L = 23.0 cm are immersed in mercury (which is a conductor). The wire is in a uniform field of magnitude B = 0.110 T. A switch (unshown) is rapidly closed and then reopened, sending a pulse of current through the wire, which causes the wire to jump upward. If jump height h = 2.10 m, how much charge was in the pulse? Assume that the duration of the pulse is much less than the time of flight. Hg -
