In a hydraulic lift, compressed air exerts a force on a small piston of radius . Due to this pressure the second piston of radius lifts a load of . The value of is
(Acceleration due to gravity )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
The principle for hydraulic lifts is based on Pascal's law. Pressure on both the piston will be same, F1A=F2A ⇒F1π×3×10-22=Fπ×5×10-22⇒F9=1875×1025⇒F=6750 N
