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

If bar(a) and bar(b) be non collinear vectors such that |bar(a)times bar(b)|=bar(a).bar(b) then the angle between bar(a) and bar(b) is

If |bar(a)|=|bar(b)|=1 and |bar(a)timesbar(b)|=bar(a)*bar(b) , then |bar(a)+bar(b)|^(2)=

If bar(a)+bar(b)+bar(c)=bar(0) then bar(a)timesbar(b)=

bar(a),bar(b),bar(c) are three unit vectors such that bar(a)xx(bar(b)xxbar(c))(1)/(2)bar(b), then (bar(a),bar(b))=(bar(a),bar(c))=(bar(b),bar(c)), are non-collinear)

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:

If bar(a)=3bar(i)-5bar(j),bar(b)=6bar(i)+3bar(j) are two vectors and bar(c) is vector such that bar(c)=bar(a)timesbar(b) then |bar(a)|:|bar(b)|:|bar(c)|=

bar(a) , bar(b) and bar(c) are three vectors such that bar(a) + bar(b) + bar(c) = bar(0) and |bar(a)| =2, |bar(b)| =3, |bar(c)| =5 ,then bar(a) . bar(b) + bar(b) . bar(c) + bar(c) . bar(a) equals

If bar(a) and bar(b) are unit vectors such that [bar(a),bar(b),bar(a)xxbar(b)] is 1/4, then angle between bar(a) and bar(b) is

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)|=
