![A device called a railgun uses the magnetic force on
currents to launch projectiles at very high speeds. An
idealized model of a railgun is illustrated in (Figure 1). A
1.2 V power supply is connected to two conducting
rails. A segment of copper wire, in a region of uniform
magnetic field, slides freely on the rails. The wire has a
0.73 m2 resistance and a mass of 7.0 g. Ignore the
resistance of the rails. At some moment, the power
supply is switched on.
