Solve the all parts of given question:
Question: The membrane of a living cell can be approximated by a parallel-plate capacitor with plates of area 4.73 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 I: What is the energy stored in such a cell membrane if the potential difference across it is 0.0721 V? J
Part II: Would your answer to part (a) increase, decrease, or stay the same if the thickness of the cell membrane is increased?
Please show all work and clearly explain each step.
A charge of -7.1 micro-Coulombs is placed at x = 0, y = 0. A charge of +18.7 micro-Coulombs is placed at x = 0, y = +30 cm. Another charge of +31.3 micro-Coulombs is placed at x = +31 cm, y = 0 cm.
