As shоwn in Fig. 2, а prоtоn is projected with speed 3 . 90 × 10 6   m s into а region with а uniform electric field parallel to the velocity of the proton and then enters a region with a uniform magnetic field which is perpendicular to the proton velocity with a magnitude B → = 0 . 300   T . Both the width of the electric region and the width of the magnetic region are 20 . 0   c m . If the surface charge density of the left large plate in the electric field region is 6 . 00 × 10 - 6   C m 2 and the surface charge density of the right large plate in the electric field region is - 6 . 00 × 10 - 6   C m 2 , (a) what is the speed of the proton when it exits from the region of the electric field; (b) what is radius of path of the proton after it enters the region of magnetic field; (c) how much time does the proton stay in the region of the magnetic field; and (d) what are the x and y components of the velocity of the proton when it exits the magnetic region? If the magnitude of the magnetic field can be changed, (e) what is the magnitude of the magnetic field if the incoming proton exits the region of magnetic field in a direction opposite to its incoming direction? (mass of a proton= 1 . 67 × 10 - 27   k g ; charge of a proton= 1 . 60 × 10 - 19   C ) fig_q18_final.jpg                                                                 Fig. 2.1                                                                                                                                                                                                                                     Fig. 2.2
