    1a. The electric field within the membrane separating the inside and outside of a biological cell is approximately 8.1 {MV/m} and is essentially uniform.If the membrane is 13 nm thick, what is the potential difference across the membrane?
    Express your answer using two significant figures

    1b. Relevant equations


    1c. The attempt at a solution

    2a.It takes 70 J to move a 10 mC charge from point A to point B.What's the potential difference Delta V {AB}?
    Express your answer using two significant figures.

    2b.k=e(delta V)
