Question
A block of steel of size 5 cm × 5 cm × 5 cm is weighed in water. If the relative density of steel is 7. Its apparent weight is :
Options
A.6 × 5 × 5 × 5 gf
B.4 × 4 × 4 × 7 gf
C.5 × 5 × 5 × 7 gf
D.4 × 4 × 4 × 6 gf
Solution
Wapp = mg − FB
Wapp = ρVg − ρwVg
= (ρ − ρw) Vg
= (7ρw − ρw) Vg = 6 ρw Vg
Wapp = ρVg − ρwVg
= (ρ − ρw) Vg
= (7ρw − ρw) Vg = 6 ρw Vg
