An electron in a computer monitor enters midway between two
An electron in a computer monitor enters midway between two parallel oppositely charged plates, as shown in Fig. 15.31. The initial speed of the electron is 6.15 x 107 m/s and its vertical deflection (d) is 4.70 mm.
(a) What is the magnitude of the electric field between the plates?
(b) Determine the magnitude of the surface charge density on the plates in C/m2.
