If `bara` is collinear with `barb`=3i + 6j + 6k and `bara.barb=27`, then `bara`=

If bara,barb,barc are three non-zero vectors which are pairwise non-collinear. If bara+3barb is collinear with barc and barb+2barc is collinear with bara , then bara+3barb+6barc is

Given that the vectors bara,barb and barc (no two of them are collinera). Further if (bara +barb) is collinear with barc,(barb+barc) is collinear with bara and |bara|=|barb|=|barc|=sqrt2 . Then the value of |bara.barb+barb.barc+barc.bara| is________

If bara barb barc are three nonzero vectors no two of which are collinear, bara+2barb is collinear with barc and barb+bar3c is collinear with bara then |bara+2barb+6barc| will be equal to

If bara,barb,barc are three non-zero vectors which are pairwise non-collinear. If bara+3barb is collinear with barc and barb+2barc is collinear with bara , then bara+3barb+6barc is: a) barc b) bar0 c) bara+barc d) bara

If bara=i+j+k,bara.barb=1 and baraxxbarb=j-k , then : barb =

Given bara, barb, barc are three non-zero vectors, no two of which are collinear. If the vector (bara + barb) is collinear with barc and (barb + barc) is collinear with bara , then : bara+barb+barc =

Given bara, barb, barc are three non-zero vectors, no two of which are collinear. If the vector (bara + barb) is collinear with barc and (barb + barc) is collinear with bara , then : bara+barb+barc =

If bara,barb and barc be three non-zero vectors, no two of which are collinear. If the vectors bara+2barb is collinear with barc and barb+3barc is collinear with bara , then ( lambda being some non-zero scalar) bara+2barb+6barc is equal to: a) lambdabara b) lambdabarb c) lambdabarc d)0

If bara = i+ 2j - 3k and barb = 3i,- j + 2k , then show that bara+barb and barb-barb are perpendicular to each other.
