Show that the pressure exerted by fluid at rest is independent of the shape of the container |
|
Answer» tion:if an object is at rest, then acc. to NEWTONS law resultant force=zeroconsider a column of fluid above that point, pressure=force/area force=mass×accelerationhere acceleration=gmass=DENSITY×height of the fluid column above that point×areasubstitute these values in p=f/a formula. p=density×h×a×g÷a p=density×h×gthis is the formula for pressure at a point in a fluid in any container. here density,h and g will not CHANGE according to container. only area will change but U dont have area in the final formula. so pressure exerted by fluid at rest is INDEPENDENT of the shape of the container. |
