A parallel plate capacitor is fully charged through a 9V battery. It has an area of A=10 cm². The plates are separated by a distance of d=0.1cm and the space between the plates is initially filled with air. We then remove the battery and subsequently insert a material with a dielectric constant of K=3 in between the plates. Upon this insertion, the potential across the plates: Select the correct answer is increased by a factor of 9 Ostays the same O is decreased by a factor of 3 is decreased by a factor of 9 is increased by a factor of 3
