Two parallel metal plates $3$m $103\mathrm{.}5$ apart have a potential difference between them of $175$ V$.$ Suppose that the separation between these two plates is much smaller than the dimension of each plate. $($In class, the instructor specified this condition as d A $.)$ The electric force exerted on a positive charge of $6\mathrm{.}41019$ C at a point midway between these two plates is approximately A$.4\mathrm{.}81018$ N$.$ B$.2\mathrm{.}41017$ N$.$ C$.1\mathrm{.}61018$ N$.$ D$.4\mathrm{.}81016$ N$.$ E$.3\mathrm{.}21014$ N$.$
