Question

Suppose you were floating in space and pointed a laser beam away from you with the intensity of 3.7246E+07 W/m^2. What would your acceleration be? Assume your total mass, including equipment, is 73.0 kg and that the force is directed through your center of mass. Hint: The change in momentum is the same as in the nonreflective case. (m/s^2)

Calculate your acceleration if it were due to the gravity of a space station with mass 1.14E+06 kg and center of mass 109.3 m away. (m/s^2)

Calculate the peak electric and magnetic fields of the laser.

Emax = (N/C)
Bmax = (T)

Explanation / Answer

sol take help a = k/r² g = k/6380² k = 6380²g so a = 6380²g/r² then a/g = (6380/r)² = [6380/(6380+285)]² = 0.916 ans The acceleration of gravity at 285 km above the Earths surface is 91.6% of that at the surface.
