29. A parallel plate capacitor with an area of A = 1 cm² and electrode separation of d = = 0.01 mm has a capacitance Co = 88.5 pF when there is vacuum between the electrodes. If a dielectric material is inserted between the electrodes and the capacitance is observed to decrease by 25%, what is the value of the material's dielectric constant k? (1) k = 1.25 Co (2) k= Co d (3) k= EO A (4) k= –22 pF (5) This situation is not physically possible 0.8
