Any good university Physics book (e.g. Haliday & Resnick or Sears) will give you an excellent start. Do you have any of those books?

What is the name of the book that you have?
Can you determine the field due to a thin disk?

Your cylinder is conductive or non-conductive? The equation above is for "non-conducting" disk

Use the disk as a "differential element" of height dz - and integrate along the length to calculate the emf at P.

I can set the integral - but I will not do that. However, as I'll help YOU to set up the integral.
Going back to the disk - what was the TOTAL amount of electric charge stored in the disk.

Look back to response #5
There is no Q there.
My Question was:
Lets try again....
the total charge is Q
in response #5 it was given the density per unit area, [MATH]\sigma[/MATH]
then
Q = A[MATH]\sigma[/MATH]
or we can just replace the value of [MATH]\sigma[/MATH] to get the answer in terms of Q
[MATH]\sigma = \frac{Q}{A} = \frac{Q}{\pi R^2 [SUB][/SUB]}[/MATH]
