What is meant by gravitational field intensity at a point due to the Earth ?

What is meant by gravitational field strength ?

Gravitation - Gravitational Field Intensity

Show that the gravitational field intensity of the earth at any point is equal to the acceleration produced in the freely falling body at that point.

The gravitational field intensity at a point 10,000km from the centre of the earth is 4.8Nkg^(-1) . The gravitational potential at that point is

The gravitational field intensity at a point 10,000km from the centre of the earth is 4.8Nkg^(-1) . The gravitational potential at that point is

Gravitational field intensity increases at height from surface of Earth.
