    Answer:


    -i – 7j

    Explanation:

    The computation of components of the force is shown below:-

    torque T = r cross F

    T = (4.00 i + 5.00 j + 0 k) X (1.00 i + 7.00 j)

    Now we will cross multiplying vectorilly

    T = 4 × (iXi) + 28 × (jXi) + 0 + 5 × (iXj)35 × (jXj) + 0

    T = 4 × 0 + 28 × (-k) + 5 × (k) + 35 × 0

    T = 28 × (-k) + 5 × (k) = -23k

    net torque |T| = 23 N – m

    direction >> negative k

    Or Simply we can do by the below method

    r × f

    28 – 5 = 23 K

    -i – 7j
