Question: A 1.92-nF parallel-plate capacitor is charged to an initial potential difference Vi = 100 V and is then isolated. The dielectric material between the plates is mica, with a dielectric constant of 5.
Part A: How much work is required to withdraw the mica sheet?
I want help to find how much work is required to withdraw the mica sheet.
