If `veca, vecb, vecc` are non coplanar vectors such that `vecbxxvecc=veca, vecaxxvecb=vecc aned veccxxveca=vecb` then (A) `|veca|+|vecb|+|vecc|=3` (B) `|vecb|=1` (C) `|veca|=1` (D) none of these

if veca,vecb,vecc are non coplanar and non zero vectors such that vecbxxvecc=veca,vecaxxvecb=vecc and veccxxveca=vecb then 1 (a) |a|=1 (b)|a|=2 (c) |a|=3 (d) |a|=4

if veca,vecb,vecc are non coplanar and non zero vectors such that vecbxxvecc=veca,vecaxxvecb=vecc and veccxxveca=vecb then 3. (a) |a|+|b|+|c| =0 (b) |a|+|b|+|c|=2 (c) |a|+|b|+|c| =3 (d) none of these

If veca, vecb,vecc are three on-coplanar vectors such that veca xx vecb=vecc,vecb xx vecc=veca,vecc xx veca=vecb , then the value of |veca|+|vecb|+|vecc| is

If veca , vecb and vecc are three vectors such that vecaxx vecb =vecc, vecb xx vecc= veca, vecc xx veca =vecb then prove that |veca|= |vecb|=|vecc|

If veca , vecb and vecc are three vectors such that vecaxx vecb =vecc, vecb xx vecc= veca, vecc xx veca =vecb then prove that |veca|= |vecb|=|vecc|

If veca,vecb,vecc be three non coplanar vectors show that vecbxxvecc,veccxxveca,vecaxxvecb are non coplanar.

If veca, vecb, vecc are any three vectors such that (veca+vecb).vecc=(veca-vecb)=vecc=0 then (vecaxxvecb)xxvecc is

If veca, vecb, vecc are non-null non coplanar vectors, then [(veca-2vecb+vecc, vecb-2vecc+veca, vecc-2veca+vecb)]=

If veca,vecb,vecc are coplanar then show that vecaxxvecb, vecbxxvecc and veccxxveca are also coplanar.

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:
