Two liquids are tested at different depths. Use g=10 N kg−1g=10\,\text{N kg}^{-1}g=10N kg−1.
The table shows the depth of each pressure sensor below the liquid surface and the density of the liquid.
| Liquid | Depth of sensor (m) | Density of liquid (kg m−3^{-3}−3) |
|---|---|---|
| A | 1.5 | 900 |
| B | 1.2 | 1200 |
Explain which sensor records the greater pressure due to the liquid. Use calculations to support your answer.
