Question

Q-17 The space surrounding a material body in which gravitational force of attraction can be experienced
is called its gravitational field. Gravitational Field intensity: The intensity of the gravitational field of a
material body at any point in its field is defined as the force experienced by a unit mass (test mass) placed
at that point. If a test mass mat a point in a gravitational field experiences a force F then I Fm​

Answer 1

Gravitational force is the force between two bodies irrespective of the presence of any objects between them,

Fg=R2GMm where G is the constant of gravitation, M and m are the masses of Earth and the object, R is the distance between the object and center of Earth.
