How would the force of gravity between the earth and the moon change if the earth had more mass?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

What would be the value of g on the surface of the earth if its mass was twice and its radius half?

What would be the value of g on the surface of the earth if its mass was twice and its radius half of what it is now? g2=8g1 Thus , the value of g on the surface of the earth would be eight times the present value.

What is the value of G at the center of Earth?

=0
g=0 at the centre of Earth.

What is acceleration due to gravity explain formula of relation between g and g and find the value of g?

The acceleration due to gravity is the acceleration experienced by an object during free fall when in vacuum due to the gravitational force of the Earth. The standard value of g is 9.8 m/s² on the surface of the earth. We know that gravitational force F = GMm/ (r+h)²

What would be the value of g on the surface?

The Value of g Depends on Location

Location	Distance from Earth’s center (m)	Value of g (m/s2)
Earth’s surface	6.38 x 106 m	9.8
1000 km above surface	7.38 x 106 m	7.33
2000 km above surface	8.38 x 106 m	5.68
3000 km above surface	9.38 x 106 m	4.53

Will the value of g be the same everywhere on the surface of the earth?

The value of g is not same everywhere on surface of earth because of the altitude or the height of the surface above the sea level is not same everywhere.

What is the exact value of G?

standard acceleration of gravity
Numerical value	9.806 65 m s-2
Standard uncertainty	(exact)
Relative standard uncertainty	(exact)
Concise form	9.806 65 m s-2
