    Answer:

    Efficiency of machine=4.9

    Explanation:

    We are given that

    Mass of load=100 kg

    Effort=20 N

    Velocity ratio=10

    We have to find the efficiency of machine.

    Load=mg=100\times 9.8=980 N

    Efficiency=\frac{Load}{effort}\times \frac{1}{velocity\;ratio}

    Using the formula

    Efficiency of machine=\frac{980}{20}\times \frac{1}{10}

    Efficiency of machine=\frac{49}{10}

    Efficiency of machine=4.9
