If `veca,vecb and vecc` are non coplaner vectors such that `vecbxxvecc=veca`, `veccxxveca=vecb` and `vecaxxvecb=vecc` then `|veca+vecb+vecc|`=

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

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

If veca,vecb and vecc are non-coplaner,then value of veca{(vecbxxvecc)/(3vecb.(veccxxveca))}-vecb.{(veccxxveca)/(2vecc.(vecaxxvecb))} is

If veca,vecb ,vecc are any three non- coplanar vectors then the equation [vecbxxvecc veccxxveca vecaxxvecb]x^(2) + [veca+vecb vecb+vecc vecc+veca] x+1 +[vecb-vecc vecc -veca veca -vecb] =0 has roots (A) real and distinct (B) real (C) equal (D) imaginary

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

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

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