Question

Assertion: Pascal law is the working principle of hydraulic lift.
Reason: Pressure `=(thrust)/(area)`
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 and reason is false.
D. If both assertion and reason are false.

Answer 1

Correct Answer - B
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.
