    The answer to your question is F = 28800 N

    Explanation:

    Data

    q₁ = q₂ = 0.004 C

    distance = r = 5 m

    k = 9x 10⁹ C

    Force = F

    Formula

    F = k q₁ q₂ / r²

    -Substitution

    F = (9 x 10⁹) (0.004) (0.004) / (5) ²

    -Simplification

    F = 144000 / 25

    -Result

    F = 28800 N

    -Conclusion

    The force of repulsion between these balloons is 28800 N
