Question

Compute all part of given question:

Question: The membrane of a living cell can be approximated by a parallel-plate capacitor with plates of area 5.17 x 10-9 m², a plate separation of 8.5 x 10^-9 m, and a dielectric with a dielectric constant of 4.5.

Part A: What is the energy stored in such a cell membrane if the potential difference across it is 0.0641 V?

J

Part B: Would your answer to part (a) increase, decrease, or stay the same if the thickness of the cell membrane is increased?

Please explain your answer. I know substitution is involved so be sure to give a detailed explanation on that as well.
