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).

  • gen physics -

    apparent ρ=7860-1000=6860 kg/m²

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