NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyA cube floats both in water and in a liquid of specific gravity of \(0.8\). Therefore,
| a. | the apparent weight of the cube is the same in water and in liquid. |
| b. | the cube has displaced an equal volume of water and liquid while floating. |
| c. | the cube has displaced an equal weight of water and liquid while floating. |
| d. | if some weights are placed on the top surface of the cube to make it just sink, the load in case of water will be \(0.8\) times of that to be used in case of liquid. |
| 1. | (a) and (c) both are correct. |
| 2. | only (d) is correct. |
| 3. | (a) and (b) both are correct. |
| 4. | (a), (b), and (c) are correct. |

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyThe loss in weight of a lead block is \(3\) times in liquid \(A\) compared to that in liquid \(B\). In both cases, the block is half immersed. If \(\rho_A, \rho_B\) be the densities of the liquids and \(\rho_L\) the density of lead, then:
| 1. | \(3\rho_A=\rho_B\) |
| 2. | \(\dfrac32\rho_A=\rho_B\) |
| 3. | \(\rho_A=\dfrac32\rho_B\) |
| 4. | \(\rho_A=3\rho_B\) |
