in the figure alongside the ink does not fall out of the dropper Because

Answer 1

please send the figure

Answer 2

Consider if the empty ink dropper is filled with air of lower barometric pressure whereas the barometric pressure outside the dropper is higher.

When the dropper is inserted into the ink bottle and on pushing the rubber, ink is sucked into the dropper.

Now the ink is present at a lower barometric pressure in the dropper hence it does not fall out. Generally the fluids does not fall out from lower tension to higher tension region
