Assertion: If the head of a right handed screw rotates with the body, the screw advances in the direction of the angular velocty.
Reason: For rotation about a fixed axis, the angular velocity vector lies along the axis of rotation.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
a
If the sense of rotation of the body changes i.e., clockwise or anti-clockwise so does the direction of angular velocity.
