Which of the following statements is correct with respect to G and g?

G is a fundamental constant, whereas g is a physical quantity and subject to change.

Both G and g can change, but g can only change if you go to a different planet.

G and g are both constant, but g is determined by the mass and radius of the Earth.

The strength of G is determined by g.

Kepler's First Law states

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

objects attract other objects with a force that is directly proportional to the product of their masses

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

Kepler's Second Law states

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

objects attract other objects with a force that is directly proportional to the product of their masses

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

Kepler's Third Law states

the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

objects attract other objects with a force that is directly proportional to the product of their masses

An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

This is a statement of which scientific law? Object attract other objects with a force that is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them.
