$(a)$ Earth can be thought of as a sphere of radius $6400\, km$. Any object (or a person) is performing circular motion around the axis of the earth due to the earth rotation (period $1$ day). What is acceleration of object on the surface of the earth (at equator) towards its centre ? What is it at latitude $(\theta )$ ? How does these accelerations compare with $g=9.8\,m/s^2$ ?
$(b)$ Earth also moves in circular orbit around the sun once every year with an orbital radius of $1.5 \times 10^{11} \,m$. What is the acceleration of the earth (or any object on the surface of the earth) towards the centre of the sun ? How does this acceleration compare with $g=9.8\,m/s^2$ ?
