    Answer:

    7.60× 10^6 V/m

    Explanation:

    electric field strength can be determined as ratio of potential drop and distance, I.e

    E=V/d

    Where E= electric field

    V= potential drop= 74.0 mV= 0.07 V

    d= distance= 9.20 nm = 9.2×10^-9 m

    Substitute the values

    E= 0.07/ 9.2×10^-9

    = 7.60× 10^6 V/m
