    Answer:

    r = 0.137 m

    Explanation:

    The electric force is given by the Coulomb equation

              F = k q₁ q₂ / r²

    where k is the constant of Coulomb that is worth 8,988 10⁹ N m²/C², q₁ and q₂ are the charges and r is the distance that separates them

             r² = k q₁q₂ / F

             r = √ k q₁q₂ / F

    let’s calculate

             r = √ (8.99 10⁹ 2.8 10⁻⁶ 7.5 10⁻⁶⁶ / 10

             r = √ (1,8879 10⁻²)

             r = 0.137 m
