Assertion: A fluid flowing out of a small hole in a vessel apply a backward thrust on the vessel.
Reason: According to equation of continuity, the product of area and velocity remain constant.

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.

Text Solution

Verified by Experts

The correct Answer is:
A
Due to small area of cross-section of the hole, fluid flows out of the vessel with a large speed and thus the fluid possesses a large linear momentum. As no external forces acts on the system, in order to conserve linear momentum, the vessel acquires a velocity in backward direction or in other words a backward thrust result on the vessel.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 : The velocity increase, when water flowing in broader pipe enter a narrow pipe. STATEMENT-2 : According to equation of continuity, product of area and velocity is constant.

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

The velocity of the liquid coming out of a small hole of a vessel containing two different liquids of densities 2rho and rho as shown in the figure is

Assertion : The equation of motion can be applied only if acceleration is along the direction of velocity and is constant. Reason : If the acceleration of a body is constant then its motion is known as uniform motion.

Two cylindrcal vesels placed on a horizontal table contain water and mercury respectively up to the same height. There is a small hole in the walls of each of the vessels at half the height of liquids in the vessels. Find out the ratio of the velocities of efflux of water and mercury from the holes. Whcih of the two jets of liquid will fall at a greater distance on the table from the vessel? Relative density of mercury with respect to water = 13.6
