What is the moment of the gravitational force of the sun on earth about the axis of its rotation about the sun ?

The rotation of earth about its axis is

Calculate the ratio of the angular momentum of the earth about its axis due to its spinning motion to that about the sun due to its orbital motion. Radius of the earth =6400 km and radius of the orbit of the earth about the sun =1.5xx10^8km.

On account of the earth rotating about its axis

Both earth and moon are subjected to the gravitational force of the sun. as observed from the sun, the orbit of the moon

The mass of the moon is about 1.2% of the mass of the earth. Compared to the gravitational force the earth exerts on the moon, the gravitational force the moon exerts on earth

Let F_1 be the magnitude of the gravitational force exerted on the Sun by Earth and F_2 be the magnitude of the force exerted on Earth by the Sun. Then:

Statement I : Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun , and the rotation of the Earth. Statement II : Earth rotates from the West towards the East once in 24 hours with respect to the Sun.

Calculate the moment of inertia of each particle in Fig. about the indicated axis of rotation.
