Rail guns can accelerate an object by using the magnetic force on a current carrying device. a rail gun is constructed to accelerate a length of copper wire, having a radius of 5.1 x 10-4 m and density,  = 8960 kg/m3. the rails have a length l = 1.0 m and are in a constant magnetic field b = 2.0 t, oriented perpendicularly to the plane defined by the rails. the wire forms an electrical connection across the rails at one end of the rails. the wire starts from rest at this end of the rails, and when triggered, a current of 10 ka flows through the wire. calculate the speed of the wire as it leaves the rail. {2.34 km/s}
