In a trapezium, if the vectors bar(BC)=lambda(AD),barP=bar(AC)+bar(BD) is collinear with bar(AD) and barP=mubar(AD) , then

If the vector bar(a)=2bar(i)+3bar(j)+6bar(k) and bar(b) are collinear and abs(bar(b))=21" then "bar(b)=

bar(a), bar(b), bar(c) are three vectors of which every pair is non-collinear. If the vectors bar(a)+2bar(b) and bar(b)+3bar(c) are collinear with bar(c) and bar(a) respectively, then bar(a)+2bar(b)+6bar(c)=

If the vectors bar(a)=2bar(i)+3bar(j)+6bar(k) and bar(b) are collinear and |bar(b)|=21 , then bar(b) equals to

Let bar(a),bar(b) and bar(c) be three non-zero vectors,no two of which are collinear.If the vectors bar(a)+2bar(b) is collinear with bar(c) and bar(b)+3bar(c) is collinear with bar(a), then bar(a)+2bar(b)+6bar(c) is equal to

bar(a), bar(b), bar(c) are three vectors of which every pair is non-collinear. If the vectors bar(a)+bar(b), bar(b)+bar(c) are collinear with bar(c), bar(a) respectively, then bar(a)+bar(b)+bar(c)=

If angle between unit vectors bar(P) and bar(Q) is 60^(0) then |bar(P)+bar(Q)| is

bar(a), bar(b) , bar(c ) are pair wise non zero and non collinear vectors. If bar(a) + bar(b) is collinear with bar(c ) and bar(b) + bar(c ) is collinear with bar(a) then find vector bar(a) + bar(b) + bar(c ) .
