In Figure (a), an electron is shot directly away from a uniformly
charged plastic sheet, at a speed of vs = 8.00 x 10^4 m/s. The
sheet is nonconducting, flat, and very large. Figure (b) gives the
electron's vertical velocity component v versus time t until the
return to the launch point. (The vertical axis is marked in
increments of 2.00 x 10^4 m/s.) What is the sheet's surface charge
density?
