Kinematics Question 63

Question: Assertion : Vector product of two vectors is an axial vector Reason : If $ \vec{v} $ = instantaneous velocity, $ \vec{r} $ = radius vector and $ \vec{\omega } $ = angular velocity, then $ \vec{\omega }=\vec{v}\times \vec{r}. $

Options:

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

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

C) If assertion is true but reason is false.

D) If the assertion and reason both are false.

Answer:

Correct Answer: C

Solution:

$ \vec{v}=\vec{\omega }\times \vec{r} $

The expression $ \vec{\omega }=\vec{v}\times \vec{r} $ it’s wrong.
