I have attached three scanned sheets of solution for this question.
Capacity is calculated using formula 1 for the first case and using formula 2 when slab is inserted. Formula 2 I have used directly but if u want the derivation of the formula then I can produce it.

A capacitor is constructed from two square, metallic plates of sides land separation d. Charges +Qand-Q are placed on the plates, and the power supply is then removed. A material of dielectric constant x is inserted a distance x into the capacitor as shown in the figure below. Assume d is much smaller than x. Suggestion: The system can be considered as two capacitors connected in parallel. (Use the following as necessary: 80, X, 1, Q. d, and x.) +...

The plates of a parallel plate capacitor are 4 cm wide and 7 cm long. The plates are separated by a 1.7-mm-thick layer of paper. a)Calculate the capacitance of the device (in pF) using the dielectric constant of paper b)Any dielectric material other than a vacuum has a maximum electric field that can be generated in the dielectric material before it physically or chemically breaks down and begins to conduct. This maximum electric field is called dielectric strength. The dielectric...
