A 0.250-m-long bar moves on parallel rails that are connected
through a 6.00 Ω resistor, as shown in Fig, so the apparatus
makes a complete circuit. You can ignore the resistance of the bar and
rails. The circuit is in a uniform magnetic field B = 1.20 T that is directed
into the plane of the figure. At an instant when the induced current
in the circuit is counterclockwise and equal to 1.75 A, what is the
velocity of the bar (magnitude
and direction)?
