a string supports a solid iron object of mass 180g totally immersed in liquid of density 800kg/m3. calculate the tension in the string if the density of iron is 8000kg/m3.

6 answers

Use the same equation as before:

F=(m-ρv)g N

where v=volume of the iron object, and
v=m/8000 m³

Be sure to convert all values into SI units.

volume= mass/density=0.180/8000=2.25x10^-5
f=(m-pv)g=(o.180-0.018)10+1.62 N

Is it correct
