Question

A solid of density 3000 kg III weighs .5 kgt in air.
Te is completely immersed in water of density
1000 kg m-?. Calculate the apparent weight of the solid
in water.
Ans. 0.4 kgf
Two spheres A and B, each of volume 100 cm
are placed on water (density = 1.0 g cm-?). The sphere A
is made of wood of density 0.3 g cm- and the sphere B is
made of iron of density 8.9 g cm-.
(a) Find : (i) the weight of each sphere, and (ii) the
upthrust on each sphere.
(b) Which sphere will float ? Give reason.
Ans.(a) (i) A - 30 gf, B - 890 gf, (ii) A - 30 gf, B - 100 gf
(b) The sphere A will float
Reason : The density of wood is less than the​
