If `bar a and bar b` are unit vectors then the vectors `(bar a+bar b)xx(bar axx bar b)` is parallel to the vector

If bar(a) is a unit vector then bar(a)xx{bar(a)xx(bar(a)xxbar(b))=

If bar(a) is a unit vector then bar(a)xx{bar(a)xx(bar(a)xxbar(b))}

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

Let bar(a) and bar(b) be unit vector.If the vectors bar(c)=bar(a)+2bar(b) and bar(d)=5bar(a)-4bar(b) are perpendicular to the each other then angle between bar(a) and bar(b) is

If bar(a),bar(b) and bar( c ) are unit vectors such that bar(a)+bar(b)+bar( c )=bar(0) , then the value of bar(a).bar(b)+bar(b).bar( c )+bar( c ).bar(a)=…………

If bar(a) and bar(c) are unit parallel vectors |bar(b)|=6 then bar(b)-3bar(c)=lambdabar(a) if lambda

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