Calculate the force of attraction between two bodies, each of

their mass is 100 kg and they are 1m apart on the surface of

the earth. Will the force of attraction be different if the same

bodies are taken on the moon, their separation remaining

constant.

The attraction between them will remain the same regardless of their position in this universe (as long as the gravitational constant remains same, which it does).

However, the net force acting on either of the bodies will change if taken to the moon. This is because the gravitational pull of the moon is weaker than that of the earth.
