Answer:
The Sun has greater Inertia
The Earth and the Sun exert the same gravitational force
Explanation:
The inertia depends on the mass, if an object has a greater mass, the inertia will be greater. In this case, the Sun has more mass than Earth, so the Sun has greater inertia. On the other hand, the gravitational force is a force that depends on the interaction of two objects. Then, the Earth and Sun exert the same gravitational force because it depends on the mass of both objects.
