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 rs= 4.0 mm, and the horizontal axis scale is set by V-¹/²= 32.9 V₁/2. What is the magnitude of the magnetic field? (ww) 0 VI/2 V1/2 (¹/2)
