Density of metallic block,
ρ=5gcmcm−3
Volume of block,
V=5cm×5cm×5cm
Upthrust force on the metallic block in water.
F1=m⋅g
=ρwV×g
[ρw=1gcm‌−3]
=Vg=5×5×5×g
=5×5×5gf
∴ Apparent weight = Weight of block - Upthrust force
‌‌=mg−5×5×5gf
‌‌=(m−5×5×5)gf
‌‌=(ρV−5×5×5)gf
‌‌=(5×5×5×5−5×5×5)gf
‌‌=5×5×5(5−1)gf
‌‌=5×5×5×4gf
