A projectile with a mass of 0.08 kg that is propelled by a rail current of 20.0
Question:
A. 0.7 km/s
B. 1.0 km/s
C. 1.4 km/s
D. 2.0 km/s
The force is proportional to the square of the current running through the railgun. For a given current, the force and the magnetic field will be constant along the entire length of the railgun. The detectors placed outside the railgun give off a signal when the projectile passes them. This information can be used to determine the exit speed vi and kinetic energy of the projectile. The projectile mass, rail current, and exit speed for four different trials are listed in the table.
