Two non-mixing liquids of densities and n(n>1) are put in a container. The height of each liquid is h. A solid cylinder floats with its axis vertical and length pL in the denser liquid. The density of the cylinder is d. The density d is equal to:
1. {2+(n+1)p}
2. {2+(n-1)p}
3. {1+(n-1)p}
4. {1+(n+1)p}
Two bodies are in equilibrium when suspended in water from the arms of a balance. The mass of one body is \(36\) g and its density is \(9\) g/cm3. If the mass of the other is \(48\) g, its density in g/cm3 will be:
1.
2.
3. \(3\)
4. \(5\)
A body of density is counterpoised by Mg of weights of density in air of density d. Then the true mass of the body is
(1) M
(2)
(3)
(4)
An iceberg of density 900 kg/ is floating in water of density 1000 Kg/. The percentage of volume of ice-cube outside the water is:
1. 20%
2. 35%
3. 10%
4. 25%
