Question

1-Does the buoyancy force when an object floats equal the weight? If yes,when you put a wood in water it submerges in half but when you put it in another liquid it submerges 1/3.Then how come are the buoyancy force=Weight when we know that Fb=p(fluid).v.g

2-When the density of an object equals the density of the fluid that it is in,does buoyant force=weight? If yes then how come it doesn't come on the top.just like last question

Please elaborate extensively and in a simple language . Thanks

Answer 1

1 buoyancy force does note equal the weigh of the object that submerges in the fluid, but it is equal to the WEIGHT OF THE FLUID REMOVED BY THE OBJECT.

Answer 2

No in this specific example the wieght equals the buyancy force in fact

Answer 3

BECUASE THE OBJECT IS FLOATING

Answer 4

Floating is not enough to say the weight of the object equals the buoyancy force

Answer 5

The mass or weight of fluid displaced = mass or weight of object. Denser fluid the object flats highr in the water.

Read about people swimming on the very dense Dead Sea.

If the densities are equal to object floats with its top level with the liquid surface.

Answer 6

copy and paste fom yahoo answe.Huh

Answer 7

Shame on you

did he? link?

Now that's better

Answer 15

Lets forget it. Will you?

Answer 16

Can you snswe my question

Answer 17

he answered it. Or rather yahoo answered it by proxy.

Answer 18

weight of floating object = weight of fluid displaced

Answer 19

if an object floats does fb=fw

Answer 20

yep

Answer 21

Note always there is also pressure factors.

Answer 22

then if fo instance a ball is half way submeged in wate but another ball is 1/3 submeged, does fb=fw in both cases

Answer 23

yep

Answer 24

that doesnt make sense since fb=pvg and v depends on how much ball is submeged

Answer 25

if the balls have equal volumes, then balls weigh different amounts

Answer 26

You know surface tension?

Answer 27

I see algebaic

Answer 28

One moe question.

Answer 29

When the density of an object equals the density of the fluid that it is in,does buoyant force=weight
