| Dec 12, 2019 at 16:09 | comment | added | aditya_stack | @HritikNarayan isn't the weight of the fluid above balanced by the forces applied by the fluid upwards which is probably because of elastic collision of fluid molecules? To maintain incompressibility? | |

| Oct 5, 2015 at 16:48 | comment | added | Hritik Narayan | You misunderstood me, there is more pressure at a lower part of the body. (It's counter-intuitive, but this doesn't necessarily have to act perpendicularly downwards on the body.) | |
| Oct 5, 2015 at 16:46 | comment | added | Faizan Nabi | You mean to say that if a body was immersed into a fluid the fluid column above the body acts perpendicularly downwards on the body. But when we study buoyant force we are said that the buoyant force is caused by the pressure differences at the top of the body and the lower part of the body. You mean to say that the body immersed experiences different magnitudes of pressure at the top and the bottom you mean to say that there is more pressure at the top than at the bottom, then the body should sink because there is actually more force trying to push it down. | |
