An electron moving in a gravitational free space enters a unifrom electric field E with an initial velocity shown in fig.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V03_C01_E01_056_Q01.png" width="80%".  (a) Find the deflection distance h in the field .  (b) Find an expression for the velocity of electron  when it just emerage from the field.  (c ) Find an expression for the total deflection distance H at a vertical screen placed at a distance l from the region of uniform field .(Assume that the field abruptly ends outside the field. ).
