Question

When a body of densityρ and volume V is floating in a liquid of density σ :
(i) its true weight is Vρg
(ii) loss in its weight is Vσg
(iii) its apparent weight is zero
(iv) its density ρ is lesser than that of liquid σ

Moderate
Solution

When a body of density ρ and volume V is floating in a liquid of density σ than buoyant force acts on it in upward direction and mg in downward direction. here as body is floating it means buoyant force completely balances mg so its apparent weight would be zero.
