An iron (ĉ = 7860 kg/m3) cube measuring 15.4 cm on a side is suspended from a wire. Find the tension in the wire when the block is completely submerged in water
(ĉ = 1000 kg/m3).

apparent ρ=7860-1000=6860 kg/m²

Tension in wire
=apparent weight
=apparent mass*g
=(0.154³)*6860*9.81 N
=246 N (approx.)
