Question

Pascal?? law is the working principle of hydraulic lift Pressure $= \frac{thrust}{arer}$

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

If both assertion and reason are true but reason is not the correct explanation of assertion

Answer 2

A hydraulic lift is an arrangement used to multiply the force. When a force is applied, hydraulic pressure is transmitted in all direction. Thus it works on the principle of Pascals laws.
