    1.
    Power, P = 10000 Watt
    Cross-sectional diameter, d= 0.02 m
    speed of light, c = 3*10^8 m/s

    Because, force due to a laser radiation beam, F = change in ...

    Solution Summary

    The solution shows the steps to find the force generated due to a laser radiation beam and work out if that can lift a given mass on Earth.
