Not sure to have well understood your question
If you want to calculate the mean distance between the two plates
But this can be found geometrically without using integrals
There are two plates, green and blue as shown in the diagram below.
The green plate can move, due to which the distance R between the plates changes.
R at a height of h will be
R=(H d2+∆d1 h)/H
What will be the equation for integral of R for complete height H. Please explain the solution. I tried to solve it but came up with log(H)-log(0) in the equation. Log 0 cannot be solved.
Thankyou for your help
