Chapter 30, Problem 14P

(a)

To determine

The explanation why the arrangement looks better if the sail is highly reflective rather than absorptive.

(b)

To determine

The proof that the force exerted by the sunlight in the spacecraft’s sail is given by PSA/(4πr2c) .

(c)

To determine

The comparison between the force on the spacecraft due to radiation pressure and force on aircraft due to gravitational force and whether the system will work.
