Question

what are the two bodies without gravitational force

Answer 1

The gravitational field gets zero at two points:

1. Centre of the earth

2. At a point INFINITY in space

so i think there is no such BODY on which g gets zero.

Answer 2

Gravity is a fundamental force of the nature which works between any two bodies in the universe without physical contact. When an object has mass, it creates a bend/warp in the spacetime. So even if they are not touching each other physically, they are actually both connected via the warped fabric of spacetime.

Modern particle physics says that every force in the universe is caused by exchange of particles between them. Gravity is caused by particles called graviton. Any two objects in the univese exchange graviton particles between them. The more the mass, the greater is the amont of exchanged gravitons. So the masses are never seperated from each other.
