If `vec(A)` is perpendicular to `vec(B)`, then

If vec(A) + vec(B) = vec(R ) and 2 vec(A) + vec(B) is perpendicular to vec(B) then

If (vec(A) + vec(B)) is perpendicular to vec(B) and (vec(A) + 2 vec(B)) is perpendicular to vec(A) , then

If vec(r ) xx vec(a) = vec(b) xx vec(a), vec(r ) xx vec(b) = vec(a) xx vec(b), vec(a) ne vec(0), vec(b) ne vec(0), vec(a) ne lamda vec(b) and vec(a) is not perpendicular to vec(b) , then vec(r ) =

If vec(A),vec(B) & vec(A)+vec(B) are three non - zero vector. Such that vec(A)+vec(B) is perpendicular to vec(B) then which of one is correct :

If vec(A),vec(B)& vec(A)+vec(B) are three non - zero vector. Such that vec(A)+vec(B) is perpendicular to vec(B) then which of one is correct :

If vec(a) is perpendicular to vec(b) and vec( c ),| vec(a) |=2, |vec(b)|=3,|vec(c )|=4 and angle between vec(b) and vec( c) is ( 2pi )/( 3) , then [ vec(a)"" vec( b) "" vec( c)] is equal to

If vec(a) and vec(b) are two vectors such that |vec(a) + vec(b)| = |vec(a)| , then prove tat 2vec(a) + vec(b) is perpendicular to vec(b) .
