Question
corresponding area of the negative plate has charge ?? ? A .
a. Is the charge on the positive plate equally on both surfaces, entirely on one surface (which?), or distributed throughout the plate? Explain how you know. Repeat for the negative plate.
b. What is the field above and below both plates? How do you know?
c. What is the E-field (magnitude and direction) in the gap between the plates? How do you know? [Use Gauss’s law or another argument.]
Two large conducting plates arranged as shown carry uniformly distributed charges. An area A of the positive plate has charge+? . A and the corresponding area of the negative plate has charge -o A Is the charge on the positive plate equally on both surfaces, entirely on one surface (which?), or distributed throughout the plate? Explain how you know. Repeat for the negative plate. What is the field above and below both plates? How do vou know? b. What is the E-field (magnitude and direction) in the gap between the plates? How do you know? [Use Gauss's law or another argument.] C.Explanation / Answer
a] It is entirely on one surface, inner surface. It is because the electric field inside a conductor has to be zero.
b] Electric field above and below both plate is zero. It can be found by electric field due to large plates,
E = summation ?/2e0 = ?/2e0 + -?/2e0 =0
c] E = summation ?/2e0 = ?/2e0 - -?/2e0 = ?/e0
Direction is upward.
