A parallel-plate capacitor with only air between the plates is charged by connecting it to a battery. The capacitor is then disconnected from the battery, without any of the charge leaving the plates. A voltmeter reads 50.0 when placed across the capacitor. When a dielectric is inserted between the plates, completely filling the space, the voltmeter reads 12.5 . What is the dielectric constant of this material?
