    Finding tension in a string from a suspended object

    Okay, so I've started from scratch and this is what I've got. Hopefully, it looks correct! Volume of cube = .000006m or .0006cm Density ρ of cube = 8.8 g/cmcm3 or 8800kg/m^3 Density ρ of milk = 1.03 g/cm^3 or 1030 kg/m^3 T=? scale +Fb-mg=0 T + ρgVdisp - mg=0 T+ 0.060564-.51744=0 T=.457N Fb=...

    Finding tension in a string from a suspended object

    This is what I did: Fb (buoyancy) = ρgVdisp Fb=1.03g/cm^3(9.8)(6cm) Fb=60.564 mg= ρ=m/v ⇒ m=ρv m= 8.8(6cm) m=52.8 Then 52.8(9.8) = 517.44 This doesn't look correct either though, so I'm not sure where to go... I understand what y'all are saying about my units, but I'm just not sure where...

    Finding tension in a string from a suspended object

    Homework Statement A 0.02 m x 0.01 x 0.03 block of copper (density = 8.8 g/cm3) is suspended submerged in milk (density = 1.03 g.cm3) by a string. How much tension is in the string? Homework EquationsThe Attempt at a Solution My initial thought for an equation was: T+Fb(buoyancy)-mg=0 T+...
