(20%) Problem 2: An electron beam is shot into a region where there is both an electric field pointing upward of magnitude E-5.1 N/C, and a magnetic field, B, as shown in the figure. While moving through the region the electron beam stays in a straight line with speed v= 340 m/s. Randomized Variables E-5.1 N/C v=340 m/s & 13% Part (a) In which direction does the electric force act on the electrons? 13% Part (b) In order to keep the electrons in a straight line, in which direction should the magnetic force act? 13% Part (c) What should the direction of the magnetic field be in order to produce the force in part (b)? & 13% Part (d) Express the magnitude of the electric force using the electric field E and the elementary charge e. A 13% Part (e) Calculate the numerical value of the magnitude of Fg, in newtons.. & 13% Part (1) Express the magnitude of the magnetic force in terms of the elementary charge e, speed v, and B, the magnitude of the magnetic field. & 13% Part (g) If the electron is continuing in a straight line, express the magnitude of the magnetic field in terms of vand E. 13% Part (h) Calculate the magnitude of the magnetic field if the electron continues in a straight line, in tesla.
