A 2.00-nF parallel-plate capacitor is charged to an initial potential
difference AV}: 100 V and is then isolated. The dielectric material
between the plates is mica, with a dielectric constant of 5.00. (a) How
much work is required to withdraw the mica sheet? (b) What is the
potential difference across the capacitor after the mica is withdrawn?
