If a,b,c are three vectors such that a + b + c = 0, |a| = 1, |b| = 2, |c| = 3 then a.b+ b.c + c.a =

If a,b,c are vectors such that a*b=0 and a+b=c

a, b, c are three vectors, such that a+b+c=0 |a|=1, |b|=2, |c|=3, then a*b+b*c+c*a is equal to

a, b, c are three vectors, such that a+b+c=0 |a|=1, |b|=2, |c|=3, then a*b+b*c+c*a is equal to

a, b, c are three vectors, such that a+b+c=0 ,|a|=1, |b|=2, |c|=3, then a*b+b*c+c*a is equal to

Let a,b,c be three vectors such that a ne 0 and a xx b = 2a xx c,|a| = |c| = 1, |b| = 4 and |b xx c| = sqrt(15) . If b - 2 c = lambda a, then lambda is equal ot

If a, b, c are three unit vectors such that a + b + c = 0 , then a.b + b.c + c.a is equal to

If a,b,c are unit vectors such that a + b + c = 0 then a.b + b.c + c + c . A=

a, b, c are three vectors such that |a| = 1, |b| = 2, |c| = 3 and b, c are perpendicular. If projection of b on a is the same as the projection of c on a, then |a-b + c| =
