An empty capacitor is capable of storing 1.0 × 10⁻⁴ J of energy when connected to a certain battery. If the distance between the plates is halved and then filled with a dielectric, how much energy could this modified capacitor store when connected to the same battery?
a) 2.0 × 10⁻⁴ J
b) 5.0 × 10⁻⁴ J
c) 1.5 × 10⁻⁴ J
d) 8.0 × 10⁻⁵ J
