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,- 1.1 mm, and the horizontal axis scale is set by V,1/2- 21.8 V12. What is the magnitude of the magnetic field? Number 0.13368 (ww) Units T 0 WE 1/2 (1/2)
