After school, several students skateboard at the nearby park. Your best friend, Erwin, is a good skateboarder and happens to fall when attempting a fancy trick. After falling, Erwin gets back up and starts repeating the trick over and over again.

A Hall probe serves to measure magnetic field strength. Such a probe consists of a poor conductor 0.103 mm thick, whose charge-carrier density is 1.11 * 1025 m-3. When a 2.89-A current flows through the probe, the Hall voltage is measured to be 3.
