You mean the $\ddot x + 2\beta \dot x + \omega^2 x = 0$?

Any progress on this problem? Could you either tell us that your problem is solved, still open or something else?

comment Which is the axis of rotation?
How do you apply torque around a point? You fix some point and apply a tangential force somewhere else. But then, you fixed an axis! If you do not fix anything, you will need to apply some tangential force on the left side (say up) and some down force on the right side. Then it will rotate about its center of mass.

comment Force on Earth due to Sun's radiation pressure
Yes, the 4 should not be there (I was thinking surface of a sphere apparently), and I forgot the $c$. So your result is correct.
