joja [24]

Answer:

Option A

Up

Explanation:

we can determine the direction of the angular velocity of a rotaing body by using the right hand rule.

The right hand rule says that if you hold the axis with your right hand and rotate the fingers in the direction of motion of the rotating body then your thumb will point the direction of the angular velocity.

Following this, curving the fingers in such a way that they depict motion from the east to north, we can see that our thumb will point upwards. This makes the direction of the angular velocity at that point in time to be up
