    Answer:

    0.2943 Nm

    Explanation:

    Work done is given a the product of force and diatance moved and expressed by the formula

    W=Fd

    Here W represent work, F is applied force and d is perpendicular distance

    Also, we know that F=mg where m is the mass of an object and g is acceleration due to gravity. Substituting this back into the initial equation then

    W=mgd

    Taking acceleration due to gravity as 9.81 m/s2 and substituting mass with 0.1 kg and distance with 0.3 m then

    W=0.1*9.81*0.3=0.2943 Nm
