1. The problem statement, all variables and given/known data
Please check picture below or attachment. http://i.imgur.com/DayoP.png 2. Relevant equations E=density/2 constant 3. The attempt at a solution I know, E=density/2 constant, but how do we get potential from eletric field and how do I find it is positive or negative? Thanks!

Recall that the electric field strength is negative gradient of the potential which is equivalent to say the potential difference V_{A}V_{B} between points A and B is[tex]V_BV_A=\int_A^B{E_s ds}[/tex]
Find the electric field between the plates first. ehild

Yeah,I did find E=density/2 constant as my eletric field, but how do I get potential?
Thanks!
