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.

I want to find the value of R. 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
