The density of water is : (a) 1000 g cm−3 (b) 1 kg m−3 (c) 1 g cm−3 (d) none of these.
(c) 1 g cm−3
A block of wood floats on water with 1/4 th of its volume above the water surface. The density of the wooden block will be?
Take, density of water = 1 gcm−3.
5. two spheres A and B , each of volume 100cm3 are placed on water (density = 1 g cm-3).the sphere A is made of wood of density 0.3 g cm-3 and sphere B is made of iron of density 8.9 g cm-3.
find - upthrust on each sphere.
