Question

When a body of density $\rho$ and volume V is floating in a liquid of density $\sigma$ :

• A. Its true weight is $V\sigma g$
• B. Loss in its weight is $V\sigma g$
• C. Its apparent weight is zero
• D. Its density $\rho$ is greater than that of liquid $\sigma$

Answer 1

The correct option is C Its apparent weight is zero

when a body of density $\rho$ and volume V is floating in a liquid of density $\sigma$ than bouyant force acts on it in upward direction and mg in downward direction.

here as body is floating it means bouyant force completely balances mg so its apparent weight would be zero.

hence option (C) is correct .
