    Answer:

    Electric field in the membrane is given as

    E = 2 \times 10^5 V/m

    Explanation:

    As we know that electric field in a region is related to its potential difference given by the formula

    E = \frac{\Delta V}{\Delta x}

    here we know that

    \Delta V = 0.10 V

    \Delta x = 0.0000005 m

    so we have

    E = \frac{0.10}{0.0000005}

    E = 2 \times 10^5 V/m
