Question 4 25 pts An electron with initial velocity vo enters a region of with a uniform field E vertically directed. The velocity vector of the particle makes an angle o with respect to the horizontal direction. Determine how high the electron will go and the horizontal range before it reaches back the same height as when it entered the region. To make it quantitative, use the following values : vo = 10' cm/s; E = 1000 V/m; v =45 degrees; m = 10 31kg,; e = 1.6*10-19C
