    Answer:

    Force on Sphere A due to B = F

    Explanation:

    The electrostatic force between the two charges is given by the Coulomb’s Law, by the following formula:

    F₁₂ = kq₁q₂/r²

    where,

    F₁₂ = Force on charge 1 due to charge 2

    k = Coulomb’s Constant

    q₁ = magnitude of charge 1

    q₂ = magnitude of charge 2

    r = distance between both the charges

    Similarly, the force on charge 2 due to charge 1 is given by the following formula:

    F₂₁ = kq₁q₂/r²

    It is clear from the formula that the force of both the charges on each other due to the other charge are same. Therefore, in our case:

    Force on Sphere A due to B = Force on Sphere B due to A

    Force on Sphere A due to B = F
