At what value of Force, can we feel the effect of gravitational force between objects
PLEASE READ THE WHOLE QUESTION AND THEN ANSWER
At what value of Force, could we feel or see the effect of gravitational pull or force between two objects.
E.g. 2 pencils kept at a very small distance (r) exert a force (F) on each other such that they are pulled by each other and stick to each other though the force is easy to overcome.
But actually, I want to see two bodies moving towards each other (ignoring Friction and Force of gravity due to earth on the objects).
