MCQ
Which of the following is a correct relation
  • A
    $_a{\mu _r} = {\,_a}{\mu _w} \times \,{\,_r}{\mu _\omega }$
  • B
    $_a{\mu _r} \times {\,_r}{\mu _w} = {\,_w}{\mu _a}$
  • C
    $_a{\mu _r} \times {\,_r}{\mu _a} = 0$
  • $_a{\mu _r}/{\,_w}{\mu _r} = {\,_a}{\mu _w}$

Answer

Correct option: D.
$_a{\mu _r}/{\,_w}{\mu _r} = {\,_a}{\mu _w}$
d
( d)$\frac{{_a{\mu _r}}}{{_w{\mu _r}}} = \frac{{{\mu _r}/{\mu _a}}}{{{\mu _r}/{\mu _w}}} = \frac{{{\mu _w}}}{{{\mu _a}}} = {\,_a}{\mu _w}$
