A capacitor with air between its plates is charged to 130 V and then disconnected from the battery. Whena piece of glass is placed between the plates, the voltage acrossthe capacitor drops to 25 V. What is the dielectric constant of the glass? (Assume the glass completely fills the space between the plates.)
