Two parallel plates having charges of equal magnitude but opposite sign are separated by .12 m. Each plate has a surface charge density of 36 nC/m^2. Determine the potential difference between the plates.(adsbygoogle = window.adsbygoogle || []).push({});

I have to admit I am at a bit of a loss on how to answer this

(lettings S represent the integral sign)

I know Delta V = -SEds

and that E is constant so

Delta V = -ESds so delat V = -Ed

but I am not sure how to find E, I know sigma =Q/A

and I dont see how Gauss' law could really work here

any light someone can shed would be greatly appreciated.
