    To solve this problem we will apply the concepts related to the Voltage depending on the Electric field and the distance where it is applied. The relationship of this relationship is given in the following form:

    V= Ed \rightarrow E = \frac{V}{d}

    Here,

    E = Electric Field

    V = Voltage

    d = Distance

    Our values are given as,

    d = 1.5mm = 1.5*10^{-3} m

    V = 4.3 mV

    V = 4.3*10^{-3}V

    Replacing at the first equation we have,

    E = \frac{4.3*10^{-3}}{1.5*10^{-3}}

    E = 2.866V/m

    Therefore the electric field in the strip is 2.866V/m
