    Answer:

    The new charge on the second object is q₂ – q₁

    Explanation:

    Given;

    charge on the first object,  q₁

    charge on the second object, q₂

    Since there is no external force on isolated system, the total charge in the system is given by;

    Q = q₁ + q₂

    q₂ = Q – q₁

    When the charge on object 1 is doubled, q₁’ = 2q₁

    let q₂’ be the new charge on object 2

    q₂’ = Q – q₁’

    q₂’ = (q₁ + q₂) – 2q₁

    q₂’ = q₁ + q₂ – 2q₁

    q₂’ = q₂ – q₁

    Therefore, the new charge on the second object is q₂ – q₁
