A proton (q=1.6x10-19C, m = 1.67x10-7kg) is accelerated from rest through a voltage of 200V before it enters a region of uniform magnetic field perpendicular to the velocity of proton, as shown. a). If the proton in the magnetic field follows a circular pass with a radius 0.4 m, what is the magnitude of the strength of the magnetic field? b). Find the magnitude and direction (left, right, up the page, down the page, into the page, out of the page) of the required electric field that would allow this proton to pass through the magnetic field undeflected.
