Question

Fluid statics problem , A metal of density 10gram per cc wights 2kg in water. Find its weight in water.

Answer 1

Explanation:

I think your question is incorrect because weight in water is given and it's asking weight in water so i'm taking that you're asking weight in water and you have given weight in air

Density=10g/cm^3

=10/1000/100^3 kg/m^3(changing g to kg and cm^3 to m^3)

=10×100×100×100/1000

=10000 kg/m^3

it's Relative density=Weight in air/loss of weight in water

10000=2/loss of weight in water

loss of weight in water=0.0002 kg

weight in water =weight in air-loss

=2 - 0.0002

=1.9998 kg
