According to the universal law of gravitation, every object attracts every other object in the universe. why can’t you feel the force of attraction between you and mars?

Becuase of the earths gravitational pull you wont feel it because the earth is pulling you already and you arent big enough to feel the pull between the 2

According to Universal Law of Gravitation, Force of attraction is inversely proportional to the square of distance between them, as distance is very large in this system, force of attraction (Gravitational Force) is so less here and we can't feel it

Hope this helps!

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
