Answer
a). Rotating angular speed about its own axis will be greater because although angle rotated is same in both case time taken is less in this case.
b). Angular speed during rotation $=\frac{2pi}{24\times3600}=7.27\times10^{-5}rad/s$
Angular speed during revolution $=\frac{2pi}{365\times86400}=2\times2^{-7}rad/s$
