1. The problem statement, all variables and given/known data The electric potential V in the space between two flat parallel plates 1 and 2 is given (in volts) by V = 1920x^2, where x (in meters) is the perpendicular distance from plate 1. What is the magnitude and direction of the electric field at x = 2.5 cm? (Take the direction perpendicular to and away from plate 1 to be positive.) 2. Relevant equations E= V/r 3. The attempt at a solution First, I converted the cm to m, and then I plugged everything in, by saying: (1920*0.025^2)/0.025= 48.0. The answer is incorrect, also the negative of 48 is incorrect. I am not sure where to go from here and there was no picture to assist. Any help would be appreciated. Thanks.
