A student working in the physics laboratory connects a parallel-plate capacitor to a battery, so that the potential difference between the plates is 270 V. Assume a plate separation of d = 1.40 cm and a plate area of A = 25.0 cm^2. When the battery is removed, the capacitor is plunged into a container of distilled water. Assume distilled water is an insulator with a dielectric constant of 80.0
Required:
a. Calculate the charge on the plates (in pC) before and after the capacitor is submerged.
b. Determine the capacitance (in F) and potential difference (in V) after immersion
c. Determine the change in energy (in nJ) of the capacitor
