Example 6: Electric field on disk’s axis z

Example 2 Consider a constant, vertical electric field somehow created in a limited region of space. An electron enters the region traveling horizontally with speed. If the region has a length L, how much will the electron be deflected at the end of the region?

Example 3 A particle with mass m and charge q is ejected from the lower of two parallel plates with velocity of magnitude as shown. If a constant electric field exists between the plates, magnitude E, where will the particle return to the lower plate? How large must L be so that the particle doesn’t strike the upper plate? (Neglect gravity.) E L x y
