    Answer:

    1. gravitational, weak nuclear, electromagnetism, strong nuclear

    2. FG/FE= Gm1m2/kq1q2

    3. the ratio remains constant

    4. 2.390×10^-43

    5. 2.266×10^-19C

    Answer:

    F = 48 N

    Explanation:

    The gravitational force between two object is given by Newton’s Gravitational Law as:

    F = Gm₁m₂/r²

    where,

    F = Gravitational Force = 12 N

    G = Universal Gravitational Constant

    m₁ = mass of first object

    m₂ = mass of second object

    r = distance between them = 6 m

    Therefore,

    12 N = Gm₁m₂/(6 m)²

    Gm₁m₂ = 432 Nm²   —————- equation 1

    Now, for r = 3 m:

    F = Gm₁m₂/(3 m)²

    using equation 1:

    F = (432 Nm²)/(9 m²)

    F = 48 N
