A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.50 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 ?
