Question

a body of density 800kg/M3 is put into the water. find the part of the body float above the surface of the water​

Answer 1

Answer:

AS we know

fraction of body immersed =

ρ

(

liquid)

ρ

(

solid)

=

1000

800

= 0.8 ( as density of water = 1000 kg m

−3

)

so percentage volume of solid cylinder inside the water = 0.8×100 = 80%

so % volume of cylinder outside the water = 100 - 80 =20

hence option (D) is correct
