Question: An unusual message delivery system is pictured in figure. A 15-cm length of conductor that is free to move is held in place between two

An unusual message delivery system is pictured in figure. A 15-cm length of conductor that is free to move is held in place between two thin conductors. When a 5.0-A current is directed as shown in the figure, the wire segment moves upward at a constant velocity. If the mass of the wire is 15 g, find the magnitude and direction of the minimum magnetic field that is required to move the wire. (The wire slides without friction on the two verticalconductors.)
