A wooden cone of mass 8.8 kg floats with its apex downwards in a liquid of RD 0.8.If the RD of wood is 0.5,what mass of steel of RD 7.8 suspended from the apex of the cone by a chord that will just be able to submerge the cone?

1)2.94kg 2)8.82kg 3)5.88kg 4)1.764kg

Answers : (1)


8.8(0.8/0.5)g+ m(0.8/7.8)g=8.8g +mg, solving for m, one obtains m=5.88kg

I am unable to present a detailed solution as I am ill. If you want explanation, please ask me.
