A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.23 T. The field is then adjusted so that an electron will follow a circular path of the same radius when it is projected perpendicularly into the field with the same velocity that the proton had. What is the magnitude of the field used for the electron? Be=

In an experiment designed to measure the Earth's magnetic field using the Hall effect, a copper bar 0.400 cm thick is positioned along an east- west direction. Assume n = 8.46 × 1028 electrons/m3 and the plane of the bar is rotated to be perpendicular to the direction of B. If a current of 8.00 A in the conductor results in a Hall voltage of 4.20 x 10¯12 v, what is the magnitude of the Earth's magnetic field at this location? µT
