किन्हीं दो शून्येतर सदिशों के लिए, सिद्ध कीजिए कि |bar(a)-bar(b)|^(2)=|bar(a)|^(2)+|bar(b)|^(2)-...

If |bar(a)+bar(b)|<|bar(a)-bar(b)| then (bar(a),bar(b)) is

(bar(a)xxbar(b))^(2)+(bar(a)*bar(b))^(2)=144 and |bar(a)|=4,|bar(b)|=

Suppose bar(a), bar(b), bar(c) be three unit vectors such that |bar(a)-bar(b)|^(2)+|bar(b)-bar(c)|^(2)+|bar(c)-bar(a)|^(2) is equal to 3 . If bar(a), bar(b), bar(c) are equally inclined to each other at an angle:

bar(a),bar(b) and bar(c) are unit vectors satisfying |bar(a)-bar(b)|^(2)+|bar(b)-bar(c)|^(2)+|bar(c)-bar(a)|^(2)=9 then |2bar(a)+5bar(b)+5bar(c)|=

If bar(a),bar(b) and bar(c) are unit vectors satisfying |bar(a)-bar(b)|^(2)+|bar(b)-bar(c)|^(2)+|bar(c)-bar(a)|^(2)=9 , then |2bar(a)+5bar(b)+5bar(c)| =

Let a and be two unit vectors and theta be the angle between them then |bar(a)+bar(b)|^(2)-|bar(a)-bar(b)|^(2)=

(bar(a)+2bar(b)-bar(c))*(bar(a)-bar(b))xx(bar(a)-bar(bar(c)))=

If (bar(a)+bar(b))*(bar(a)+bar(b))=|bar(a)|^(2)+|bar(b)|^(2),bar(a)!=0,bar(b)!=0 , then

If a and b are unit vectors such that |bar(a)timesbar(b)|=bar(a)*bar(b) then |bar(a)-bar(b)|^(2)=

If [bar(a)+2bar(b)2bar(b)+bar(c)5bar(c)+bar(a)]=k[bar(a)bar(b)bar(c)]
