Question

Why do we not feel gravitational force between us and a person sitting closely?
A. It is negligible as compared to gravity of Earth
B. Gravitational force is only applicable to plants
C. It is applicable only when there is large distance between two objects
D. All of the above

Answer 1

Hint: As we all know that the gravitational force of us is nothing when we compare with the gravitational force of the Earth. Or, the gravitational force is not a strong force unless the presence of the huge masses.

Complete step by step answer:
Unless enormous masses are present, gravitational force is a weak force. Humans have modest masses, hence the gravitational pull they exert is also small and inconsequential in comparison to that exerted by Earth. As a result, there is a gravitational attraction between two people sitting close together, but it is insignificant and cannot be felt.

Or in other words, we can't feel the gravitational force since your mass is so small in comparison to that of the Earth. Because every object experiences the same gravitational force from the Earth, they all fall at the same rate (in a vacuum). We have air on Earth. Some objects will fall more slowly than others due to air resistance.

As for example- When we sit in a chair, you are subjected to two forces: the gravitational field of the Earth dragging us below and the force of the chair pushing you upward. You will never feel the force of gravity pushing on your body in the same way that a contact force would.Therefore, the gravitational force is negligible as compared to gravity of Earth, that’s why we do not feel the gravitational force between us and a person sitting closely.

Hence, the correct option is A.

Note: Because our neurological systems are divergent, we don't 'sense' gravity. Our bodies detect differences and adjust to constant values. Our perception of 'down' is continuous because we're always experiencing the same gravitational force, and it's not communicated to our brain as anything to be concerned about.
