If the electric field between plates (A) is 1.0 × 10³ N/C in the + xdirection, what is the horizontal deflection (Δx) of the beam as it exits the region between plates (A)?

After the electrons in Example 16.9 pass through the anode, they are moving in the z-direction at a speed of 8.4 × 10⁶ m/s. They then pass between a pair of vertical parallel plates 

(A) (see Fig. 16.39) and then between a pair of horizontal parallel plates 

(B). All four of these plates are squares 2.50 cm on a side. The plates of each pair are separated by 1.50 cm.
