A parallel plate capacitor of area A and separation d is provided with thin insulating spacers to keep its plates aligned in an environment of fluctuating temperature. If the coefficient of thermal expansion of material of the plate is `alpha`, find the coefficient of thernal expansion `(alphas)` of the spacers in order that the capacitance does not vary with temperature. (Ignore effect of the spacers on capacitance.)
