Question

36. A man rides in an elevator with vertical acceleration a. He
swings a bucket of water in a vertical circle of radius R.
With what angular velocity must he swing the bucket:so
that no water spills -
(1) 02/(a+9)/R (2) 2 (g-a)/R
(3) o2 (Va? + g? /R)1/2 (4) oz Ja-9)/R
Plzz anss it ​

Answer 1

Answer:

$\huge\mathbb{\orange{QUESTION-}}$

You swing a bucket of water in a vertical circle of radius 1.9 m. What speed must the bucket have if it is to complete the circle without any water spilling?

$\huge\mathbb{\orange{SOLUTION-}}$

$\large\underline{\underline{\sf Given:}} </p><p>$

Radius of circle (r) = 1.9m

$\large\underline{\underline{\sf To\:Find:}} </p><p>$

Speed must the bucket have if it is to complete the circle without any water spilling (v).

$\large\underline{\underline{\sf Formula\:Used:}}$

FormulaUsed:

Minimum centripetal acceleration is g = 9.8m/s²

2

=18.62

18.62

⟹v=4.31m/s

$\huge\mathbb{\orange{ANSWER-}}$

Speed must the bucket have if it is to complete the circle without any water spilling is {\bf \red{4.31\:m/s}}4.31m/s
