    Answer:

    C. 80N

    Explanation:

    Mechanical advantage

    = Output force /input force

    Given

    M.A = 4

    Input force = 20N

    Output force = ?

    Therefore

    4 = output force /20

    Cross multiply

    Output force = 20 x 4

    = 80N

    Answer:80N

    Explanation:

    Mechanical advantage=4

    Input force=20N

    Output force=?

    mechanical advantage(ma)=(output force) ➗ (input force)

    4=(output force) ➗ 20

    Output force=4 x 20

    Output force=80N
