38 In Fig. 23-48a, an electron is shot directly away from a uni- formly charged plastic sheet, at speed v, = 2.0 x 10° m/s. The sheet is nonconducting, flat, and very large. Figure 23-48b gives the electron's vertical velocity component v versus time t until the return to the launch point. What is the sheet's surface charge density? 12 -e t (ps) (a) (b) v (10 m/s)
