Ans. 04 on water (density = 10gcm). The sphere A
Two spheres A and B. each of volume 100 cm
is made of wood of density 0-3 g cm and the sphere is
(a) Find : (i) the weight of each sphere, and (ii) the
are placed on water (density
made of iron of density 8.9 g cm
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
