Assertion :Pascal's law is the working principle of a hydraulic lift Reason: Pressure is thrust per unit area
Open in App
Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.A hydraulic lift for automobiles is an example of a force multiplied by hydraulic press, based on Pascal's principle. The fluid in the small cylinder must be moved much further than the distance the car is lifted.Thrust is the total force acting perpendicular to the surface. The unit of thrust is Newton. The force acting (thrust) per unit area is called pressureBoth are correct statement but reason is not the correct explanation of assertion .
