Usually that orientation is defined with reference to direction of velocity. And object at rest as you said is at zero velocity (wrt own frame). So in which direction will you orient this velocity of zero magnitude? Therefore I guess, that such an object at rest will have many lengths each in each direction. <br><div class="gmail_quote" dir="auto"><div dir="ltr"><br></div><div dir="ltr">Regards,</div><div dir="ltr"><br></div><div dir="ltr">Tufail </div><div dir="ltr"><br></div><div dir="ltr"><br></div></div></div></div>
