Question

a solid object of mass 50kg and volume 100cm3 is put in water. will the object float or sink. give reason for your answer

Answer 1

A solid object of mass 50 g and volume 100 cm3 is put in water. Wilect flol the objat or sink? Give reasons for your answer.

Density of solid object = Mass/Volume = 50g/100 cm^2 = 0.5g/cm^2

Density of water =1g/cm^2 

Thus, density of solid object is less than density of water, so the object will float in the water

Answer 2

Volume of body is 100 * 10^-6 = 10^-4
Density will be 50 / 10^-4 = 50* 10^4 = 5,00,000
Which is more than that of water so it will sink
