Physics (AS & A Level) · Oct / Nov 2022 · Paper 12 · Question 16

The diagram shows two vessels, P and Q, both with sides inclined at 45° to the horizontal. Vessel P tapers outwards and vessel Q tapers inwards, as shown. Both vessels contain a liquid. The depth of the liquid in the vessels is the same. The liquid in vessel P is twice as dense as the liquid in vessel Q. What is the ratio (pressure due to the liquid on the base of P) / (pressure due to the liquid on the base of Q)?

1. A2/1
2. B√2/1
3. C1/√2
4. D1/2
