The movable cylindrical pistons \(P_1\) and \(P_2\) of a hydraulic lift are of radii \(2 \mathrm{~m}\) and \(R\) respectively. A body of mass \(32 \mathrm{~kg}\) on piston \(P_2\) is supported by a body of mass \(2 \mathrm{~kg}\) placed on piston \(P_1\). The value of \(R\) is
- A \(8 \mathrm{~m}\)
- B \(32 \mathrm{~m}\)
- C \(2 \mathrm{~m}\)
- D \(16 \mathrm{~m}\)
Answer & Solution
Correct Answer
(A) \(8 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
The pistons \(P_1\) and \(P_2\) of a hydraulic lift are shown below Using Pascal's law, pressures at piston \(P_1\) and \(P_2\) will be equal…
