Solution Verified by Toppr

Correct option is D)

Given data,

d 1 ​ =8×10 −3 m v 1 ​ =0.4ms −1 h=0.2m

According to equation of motion,

v 2 ​ = v 1 2 ​ +2gh ​ = (0.4) 2 +2×10×0.2 ​ ≈2ms −1

∴ According to equation of continuity

a 1 ​ v 1 ​ =a 2 ​ v 2 ​ π×( 2 8×10 −3 ​ ) 2 ×0.4=π×( 2 d 2 ​ ​ ) 2 ×2 d 2 ​ =3.6×10 −3 m

Question

Water is flowing continuously from a tap having an internal diameter

8 × 10 − 3 m

. The water velocity as it leaves the tap is

0.4 m s − 1

. The diameter of the water stream at a distance

2 × 10 − 1 m

A 5 × 10 − 3 m B 7.5 × 10 − 3 m C 9.6 × 10 − 3 m D 3.6 × 10 − 3 m Open in App Solution

The correct option is A

3.6 × 10 − 3 m D i a m e t e r = 8 × 10 − 3 m v 1 = 0.4 m / s v 2 = √ v 2 1 + 2 g h = √ ( 0.4 ) 2 + 2 × 10 × 0.2 = 2 m / s A 1 v 1 = A 2 v 2 π ( 8 × 10 − 3 2 ) 2 × 0.4 = π × d 2 4 × 2 ⇒ d ≈ 3.6 × 10 − 3 m . Suggest Corrections 6
