Question

if an object has a density of 2.5 g/cm3 and it is placed in a tank of water, will the object float or sink in water

Answer 1

`\text{Given that,}\\\\\text{Density of the object,}~~ \rho = 2.5 ~ \text{g~cm}^(-3) = 2500 ~\text{kg} ~\text{m}^(-3) \\\\\text{Density of the object is greater than the density of water,}~ \left(\rho_w = 1000 ~ \text{kg} ~ \text{m}^(-3)\right) .\\\\\text{Hence, the object will sink in water.}`
