What is the electrostatic potential difference between the two sheets?
Suppose there are two large parallel sheets of charge separated by a distance d, small compared to the size of the sheets. The area of each sheet is A. The distance d is small enough that the sheets can be treated as if they were infinite in extent.
The amount of charge per unit area in the sheets are +p and -p respectively. Express all your answers for this problem in terms of the given parameters (p, d, A) and (if needed) universal constants.
When things have settled down, what is the electrostatic potential difference between the two sheets?
The plate containnng negative charage is earthed so that its potential is zero.
Again we can take the lines of force are stright through out since the sheets are larage.
P.d between the plates = d to zero ∫ – E dr = ∫ – (p/ξok) dr = – (pd/ξok)
V = – (pd/ξok)

16 Most Requested Songs $4.26 It’s been suggested that almost as many baby boomers were conceived to the romantic sounds of Johnny Mathis’s voice as to Sinatra’s–and when you consider that Johnny’s Greatest Hits stayed on Billboard’s Top 40 chart for 178 weeks beginning in ’58 (that’s more than twice as long as Dark Side of the Moon, folks!), it’s easy to understand why. Sony has used this “16 Most Requested” routine on a num… |

The storytelling and animation draw on everything from Ratatouille and classic fairytales to Shakespeare, Jonathan Swift, Indiana Jones, and, in its action sequences, even Bourne and Bond.
