Unformatted text preview: 8 milliwatts. What is the magnitude of the electric field in the laser beam? 489.675 490 N/C 3. 2/2 points Question: MI3 24.6.X.011 Since force is dp / dt , the force due to radiation pressure reflected off of a solar sail can be calculated as 2 times the radiative momentum striking the sail per second. In the vicinity of Earth's orbit around the Sun, the energy intensity of sunlight is about 1500 W/m 2 . What is the approximate magnitude of the pressure on the sail? (For comparison, atmospheric pressure is about 10 5 N/m 2 .) 1e5 1.00e05 N/m 2 Ch24 HW4 F2010 (Homework) Stefan Coreth PY 208, section 002M, Fall 2010 Instructor: Laura I.
