Find the dielectric constant of this glass

Reference no: EM13661004

A capacitor with air between its plates is charged to 90 V and then disconnected from the battery. When a piece of glass is located between the plates, the voltage across the capacitor drops to 25Volt.

Find the dielectric constant of this glass? (Suppose the glass completely fills the space between the plates)
