Q. Which of the following is a correct relation
A) $\ _{a}\mu_{r} = \ _{a}\mu_{\omega} \times \ _{r}\mu_{\omega}$
B) $\ _{a}\mu_{r} \times \ _{r}\mu_{\omega} = \ _{\omega}\mu_{a}$
C) $\ _{a}\mu_{r} \times \ _{r}\mu_{a} = 0$
D) $\ _{a}\mu_{r}/\ _{\omega}\mu_{r} = \ _{a}\mu_{\omega}$
Explanation
(d) $\frac{\ _{a}\mu_{r}}{\ _{w}\mu_{r}} = \frac{\mu_{r}/\mu_{a}}{\mu_{r}/\mu_{w}} = \frac{\mu_{w}}{\mu_{a}}{= \ }_{a}\mu_{w}$
