Assertion: The velocity of flow of a liquid is smaller when pressure is larger and vice versa.
Reason: According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the total energy per unit mass remains constant.

Options

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

Answer

A

Explanation

According to Bernoulli.s theorem. `P+1/2 rho v^2` = constant i.e. when velocity is large, the pressure is less in a stream line flow of an ideal liquid through a horizontal tube.
