Physics · Pressure due to a fluid column, Pascal's law and its applications, effect of gravity on fluid pressure
Assertion Pascal's law is the working principle of hydraulic lift. Reason Pressu
Assertion Pascal's law is the working principle of hydraulic lift. Reason Pressure \( =\frac{\text {thrust}}{\text {area}} \)
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Assertion is correct: Pascal's law states that pressure applied to an enclosed fluid is transmitted equally, which is the principle behind hydraulic lifts. Reason is also correct: pressure is defined as thrust per unit area. However, Reason is a general definition and does not specifically explain why Pascal's law applies to hydraulic lifts; it does not mention the transmission of pressure change. Hence, both are true but Reason is not the correct explanation.
