In an experiment designed to measure the magnitude of a uniform magnetic field, electrons are accelerated from rest through a potential difference of 350 V (think of problem 7 in hw 3). The electrons travel along a curved path because of the magnetic force exerted on them, and the radius of the path is measured to be 7.5 cm. If the magnetic field is perpendicular to the beam, a. What is the magnitude of the field? b. What is the angular speed of the electrons?
