    Answer:

    2.6 cm

    Explanation:

    Hookes Law said

    F = c ∆x

    F = Force

    c = elasticity constant of the spring/ wire

    ∆x = change in the length

    5 = c * 0.65

    c = 5/0.65

    if we change the Force to 20 then

    20 = c ∆x

    20 = (5/0.65) * ∆x

    ∆x = 20 * 0.65/5

    ∆x = 2.6 cm
