Two solids P and Q float in water. It is observed that P floats with half of its volume immersed and Q floats with (2^(rd))/3 of its volume immersed. The ratio of densities of P andQ is: |

Answer» `4//3` wt. of body = wt of water displaced for body P. `v_(p)p_(p).G=(V_(P))/2p_(w).grArrp_(P)=(p_(w))/2` For body Q. `V_(Q)p_(Q).g=2/3V_(Q).p_(w)grArrp_(Q)=2/3p_(w)` `therefore(p_(P))/(p_(Q))=((p_(w))/2)(2/3p_(w))=3/4` So CORRECT choice is (B). |
