Two large charged plates of charge density +45µC/m² face each other at a separation of 7 mm. Choose
coordinate axes so that both plates are parallel to the xy plane, with the negatively charged plate located
0 and the positively charged plate at z = +7 mm. Define potential so that potential at z =
at z =
is zero (V(z = 0) = 0).
Hint
a. Find the electric potential at following values of z:
– 7 mm:
o potential at z =
- 7 mm)
V(z =
o V.
o potential at z =
+ 6 mm:
V(z = + 6 mm)
30494
V.
o potential at z =
V(z = + 7 mm)
+ 7 mm:
35577
o V.
o potential at z =
+ 9.6 mm:
V(z = + 9.6 mm)
V.
b. An electron is released from rest at the negative plate. With what speed will it strike the positive
plate?
The electron will strike the positive plate with speed of
m/s.
