I have the statement, variables and given/known data in the picture along with relevant equations and solution attempt.
The Attempt at a Solution
I think I did the first part right. But I'm unsure about part B. The distance between the plate t is different between the stationary plate above than the distance below the plate to the stationary plate. Computing using the different distances give me a different value. I'm unsure what I'm doing wrong or what assumption is incorrect.
Any help would be appreciated. Thanks. :]
