Question

a body whose volume is 100cm³ has mass 1kg find its weight in water when completely immersed.​

Answer 1

Answer:

As volume is 100cm

3

and weighs 1000 gm as (1kgf=9.8N=1kg×g(9.8)), so its density is 10gm/cm

3

.

So the body sinks in water. It displaces 100cm

3

of water, whose density is 1gm/cm

3

.

So the weight of water displaced = 100×1=100gm.

As the displaced water acts as buoyant force, the weight of body in water is (1000-100) = 900 gms = X.

Hence, the answer is X/100 = 9.
