While in outer space, a small however powerful, spherical shaped light source is turned on with us. The light source delivers 1.00 kW/m2 at1.00 cm from its center. There is a small particle of space dust at rest, 10.0 cm away from the center of the light source. The particle of space dust has a mass of 1.00 m g, a diameter of 1.00 m m, and is perfectly reflecting. Suppose that the piece of space dust behaves like a flat disc at right angles to the light rays.
1. What is the amplitude of the magnetic field that the dust particle sees?
2. What is the speed of the dust particle 1.00 s after the light is turned on?
3. What is the amplitude of the electric field that the dust particle sees?
