A laboratory team is checking whether a small probe will float in either of two liquids. The probe has a mass of 84 g and a volume of 100 cm3. The densities of the liquids are shown in the table.
| Liquid | Density in g/cm3\text{g/cm}^{3}g/cm3 |
|---|---|
| A | 0.75 |
| B | 0.90 |
Use ρ=mV\rho=\dfrac{m}{V}ρ=Vm.
Calculate the density of the probe.
The probe is placed in each liquid in turn.
Name the liquid in which the probe floats.
Give a reason for your answer.
