Short Answer

Expert verified

This answer proves that W×S is a polar vector.

Step by step solution

01

Given information.

Matrix definitions are given.

02

Definition of transformation laws.

Define the transformation laws.

Wi'=aijWjSi'=(detA)aijSj

03

Define the transformation laws.

Write the transformation laws assuming and are axial and polar vectors.

Wi'=aijWjSi'=(detA)aijSj

04

Continue the evaluations.

Write the implication of the transformation laws.

W'×S'α=ε'αβγWβ'Sγ'=detAaαiaβjaγkεijkaβmwmdetAaγmSn=detA2aciεijkwjSk=aαiW×SI

This implies that W×S is a polar vector.
