Question

Which of the following statements is correct with respect to G and g? *
1 point
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.

Answer 1

The correct option is 1 i.e.  G is a fundamental constant, whereas g is a physical quantity and subject to change.

• The acceleration on an object due to the gravity of a body is represented by g.
• The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G.
• The relation between G and g is not proportional, i.e. they are independent entities.
• g changes from place to place in universe.  Acceleration due to gravity of the earth is 9.8 m/s2.
• Whereas the value of G is constant at any point in this universe unlike g.
