    Answer:

    Greatest pressure on the ground is 1962 Pa

    Explanation:

    As we know that pressure is ratio of force and area

    so we can write its equation as

    P = \frac{F}{A}}

    now here we need to find the greatest pressure on the ground

    here force is due weight of the object and area must be minimum in contact with the ground

    F = mg

    F = 100(9.81)

    F = 981 N

    Now minimum area of contact with the ground is

    A = 0.50 \times 1 = 0.5 m^2

    now maximum pressure is given as

    P = \frac{981}{0.5}

    P = 1962 Pa
