Question Guide – Pressure – Hydraulic Press

Question:
In the diagram shown below, Syringe A is connected to Syringe B by a connecting tube. Both syringes and the connecting tube are completely filled with an incompressible fluid X. The diameter of the piston in Syringe B is twice the diameter of the piston in Syringe A. If a force F is applied on the piston in Syringe A, the force experience by the piston in Syringe B is

Solution:
The pressure exerted in one piston will be transmitted to the other piston. Thus, pressure A equals to pressure B. Since the syringe is circular,
Expanding on O Level Physics Pressure Formula
As the question indicated the diameter of the piston in Syringe B is twice the diameter of the piston in Syringe A, then Diameter of Syringe B equals to twice of diameter of Syringe A

Solution for the Force on Syringe B

Thus, Answer is D.
