Which gravitational force field diagram is drawn correctly?

Figure (B)

Explanation:

The gravitational force per unit mass at a point is called gravitational field strength. Mathematically, it can be written as :

Since,

Then,

g is gravitational field strength or acceleration due to gravity

The gravitational force field diagram is shown in figure (B). This is because the gravitational force is an attractive force and is directed towards the center of earth. As we go closer to earth, we will experience a larger force. Similarly, as we go away from the earth, then we will experience smaller force.
