Question
Transcribed Image Text:An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it
undergoes uniform circular motion. The figure gives the radius r of that motion versus V1/2. The vertical axis scale is set by r,= 2.6
mm, and the horizontal axis scale is set by V,1"/2= 49.4 V1/2. What is the magnitude of the magnetic field?
