Statement I : The velocity increases, when water flowing in broader pipe enter a narrow pipe.
Statement II : According to equation of continuity, product of area and velocity is constant.

Very Easy

A

If both statement I and statement II are true and statement II is the correct explanation of statement I
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

Solution

In a stream line flow of liquid, according to equation of continuity av = constant.
Where a is the area of cross section and v is the velocity of liquid flow. When water flowing in a broader pipe enters a narrow pipe, the area of cross section of water decreases therefore the velocity of water increases.
