A cube of balsa wood (side length = 0.25 m) is tied with a string to the bottom of a waterfilled
container. The wood is completely immersed. What is the tension in the string?

  • physics -

    T=F(buoyancy) –mg =
    = ρ(water)Vg - ρ(balsa)Vg=
    =Vg[ρ(water) - ρ(balsa)] =
    =0.25³•9.8(1000 – 160)=129 N
