If the vectors `veca` and `vecb` are mutually perpendicular, then `vecaxx{vecaxx{vecaxx(vecaxxvecb)}}` is equal to

If the vectors veca and vecb are mutually perpendicular, then veca xx {veca xx {veca xx {veca xx vecb}} is equal to:

vecaxx(vecaxx(vecaxxvecb)) equals

If |veca|=2 and |vecb|=3 and veca.vecb=0, " then " (vecaxx(vecaxx(vecaxx(vecaxxvecb)))) is equal

If (vecaxxvecb)xxvecc=vecaxx(vecbxxvecc) then

If vecb is a unit vector, then (veca. vecb)vecb+vecbxx(vecaxxvecb) is a equal to

If veca, vecb are non zero vectors, then ((vecaxxvecb)xxveca).((vecbxxveca)xxvecb) equals

If |veca|=2, |vecb|=5 and veca*vecb=0 , then veca xx (vecaxx(vecaxx(vecaxx(vecaxx(veca xx vecb))))) is equal to :

Vectors 3veca-5vecb and 2veca + vecb are mutually perpendicular. If veca + 4 vecb and vecb - veca are also mutually perpendicular, then the cosine of the angle between veca nad vecb is

If veca is perpendicular to vecb then the vector vecaxx[vecaxx{vecaxx(vecaxxvecb)}] is equla (A) |veca|^2vecb (B) |veca|vecb (C) |veca|^3vecb (D) |veca|^4vecb

If veca,vecb and vecc are coplaner, then what is (2vecaxx3vecb).4vecc+(5vecbxx3vecc).6veca equal to?
