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 non coplanar and non zero vectors such that vecbxxvecc=veca,vecaxxvecb=vecc and veccxxveca=vecb then 2. (a) |a|-|b|+|c| =4 (b) |a|-|b|+|c|=2/3 (c) |a|-|b|+|c| =1 (d) none of these

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

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 three non-zero vectors such that veca + vecb + vecc=0 and m = veca.vecb + vecb.vecc + vecc.veca , then:

If veca, vecb, vecc are non coplanar non null vectors such that [(veca, vecb, vecc)]=2 then {[(vecaxxvecb, vecbxxvecc, veccxxveca)]}^(2)=

If veca, vecb, vecc are any three non coplanar vectors, then (veca+vecb+vecc).(vecb+vecc)xx(vecc+veca)

If veca,vecb,vecc be three vectors such that [veca vecb vec c]=4 then [vecaxxvecb vecbxxvecc veccxxveca] is equal to

If veca, vecb, vecc are three non coplanar, non zero vectors then (veca.veca)(vecbxxvecc)+(veca.vecb)(veccxxveca)+(veca.vecc)(vecaxxvecb) is equal to

veca,vecb,vecc are non zero vectors. If vecaxxvecb=vecaxxvecc and veca.vecb=veca.vecc then show that vecb=vecc .
