Question

a solid body of mass 5kg and density 5000kg/m cube and is immersed completely in aliquid if density 1000/metre cube find the upthrust acting​

Answer 1

Answer:

A solid of density 5000 Kg m

−3

weight 0.5 Kgf in air. It is completely immersed in water of density 1000 Kg m

−3

. Calculate the apparent weight of the solid in water.

Step-by-step explanation:

Density ρ = 5000 kg/m

3

Weight = 0.5 kg f in air

mass M = 0.5 kg

Volume V = M / ρ

= 0.5 / 5000 = 10

−4

m

3

mass of water displaced = V

∗

density of water

= 10

−4

∗1000 = 0.1 kg

Apparent weight = wt in air - wt of water displaced

= 0.5 kg f - 0.1 kg f

= 0.4 kg f
