MAKE DIAGRAMS A REASONABLE SIZE3. An electron accelerates from rest eastward in a horizontally directed electric field through a potential difference of 46 V. The electron then leaves the electric field and moves into a magnetic field of magnitude 0.20 T. directed into the page, and the mass of the electron is 9.11 X 10"1 kg. 3) Calculate the initial speed of the electron upon entering the magnetic field. b) Calculate the magnitude and direction of the magnetic force on the electron. 0) Calculate the radius of the electrons circular path. 3-; 'I: )I'. )I: x I - x x K I V _ +y 1 x x K )t 4.
