(II) Suppose electrons enter the uniform electric field mid- way between two plates, moving at an upward 45° angle as shown in Fig. 21–-59. What maximum speed can the elec- trons have if they are to avoid striking the upper plate? Ignore fringing of the field. - 6.0 cm ZE=5.0× 10³ N/C [1.0 cm FIGURE 21-59 Problem 58.
