# Radiation Pressure to Lift

1. You have a laser with an output of 10,000 watts in a .02m diameter beam. Find the radiation pressure.

2. If you have a reflective surface of mass .002kh on the earth, can you lift this with the laser?

#### Solution Preview

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.
