Assertion: Vector product of two vectors...

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)xxvec(r )`.

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 aseertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C

`vec(v) = vec(omega)xxvec(r )`
The expression `vec(omega)=vec(v)xxvec(r )` is wrong.
