Electric Forces and Fields

Surface Charge Density


<div class="wp-block-create-block-problemblock">Two parallel charged plates, one with a surface charge density of ##\eta_1## = 40 ##\frac{nC}{m^2}## and another, ##\eta_2## = -60 ##\frac{nC}{m^2}##.  Find the total electric field between the plates.  (note this is not a capacitor)</div>
