Question: An object of weight $ W $ and density $ \rho $ is dipped in a fluid of density $ {\rho _{1}} $ . Its apparent weight will be

Options:

A) $ W(\rho -{\rho _{1}}) $

B) $ W\left( 1-\frac{{\rho _{1}}}{\rho } \right) $

C) $ \frac{(\rho -{\rho _{1}})}{W} $

D) $ W(\rho -{\rho _{1}}) $

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Apparent weight=True weight-eight of liquid displaced

$ \therefore W-\frac{W}{p}{\rho _{1}}=W\left( 1-\frac{{\rho _{1}}}{\rho } \right) $
