    The working equation to be used for this is written below:

    E = kQ/d²

    where

    E is the electric field

    k is a constant equal to 8.99 x 10⁹ N m²/C²

    Q is the charge

    d is the distance

    The charge for a proton is equal to 1.6021766208*10⁻¹⁹ C. Substituting the values:

    E = (8.99 x 10⁹ N m²/C²) (1.6021766208*10⁻¹⁹ C) / (0.009 m) ²

    E = 1.778*10⁻⁵ N/C
