Question

Suppose a disc is rotating counter clockwise in the plane of the paper then
1) It's angular velocity vector will be perpendicular to the page pointing up out of the page
2) It's angular velocity vector will be perpendicular to the page pointing inwards
3) It's angular velocity vector acts along the tangent to the disc
4) None of the above is correct​

Answer 1

Answer:

2) is the correct option...✔

Answer 2

Suppose a disc is rotating counter clockwise in the plane of the paper then It's angular velocity vector will be perpendicular to the page pointing up out of the page.

Explanation:

A disc rotates along the clockwise direction and direction of angular velocity is downwards and this can be determined using right hand rule.

Hence,

Option (a) It's angular velocity vector will be perpendicular to the page pointing up out of the page is correct .
