A question has occurred to me during preparation for a Physics exam. My textbook does a good job of discussing a capacitor charged equal but opposite. But I want to take it a step further. My question is how to calculate the E field between 2 plates of opposing charge that have unequal magnitudes.
For example; if I have two plates of σ and -5σ a distance x apart, what would the E field be at x/2 ? Would the magnitude of the E field be constant for any point between the plates, as it is with a capacitor? Is this a simple superposition problem where I should create a Gaussian cylinder and find E field for both adding them together or is it something else? I am definitely over thinking this one.
I feel like this is exactly the type of curve ball my professor might throw at us on Monday. Any help is much appreciated. I have spent too much time thinking about this.
