If `vecaxx[vecaxx{vecaxx(vecaxxvecb)}]=|veca|^4 vecb` how are `veca and vecb` related? (A) `veca and vecb` are coplanar (B) `veca and vecb` are collinear (C) `veca` is perpendicular to `vecb` (D) `veca` is parallel to `vecb` but `veca and vecb` are non collinear

If |veca+vecb|=|veca-vecb| show that veca_|_vecb .

If vecaxx(vecaxxvecb)=vecbxx(vecbxxvecc) and veca.vecb!=0 , then [(veca,vecb,vecc)]=

If vecasxxvecb=0 and veca.vecb=0 then (A) veca_|_vecb (B) veca||vecb (C) veca=0 and vecb=0 (D) veca=0 or vecb=0

If (vecaxxvecb)xxvecc=vecaxx(vecbxxvecc), Where veca, vecb and vecc and any three vectors such that veca.vecb=0,vecb.vecc=0, then veca and vecc are

Show that |veca|vecb+|vecb|veca is perpendicular to |veca|vecb-|vecb|veca for any two non zero vectors veca and vecb.

Show that |veca|vecb+|vecb|veca is perpendicular to |veca|vecb-|vecb|veca for any two non zero vectors veca and vecb.

Prove that: vecaxx[vecbxx(veccxxveca)]=(veca.vecb)(vecaxxvecc)

If veca and vecb are two non collinear vectors and vecu = veca-(veca.vecb).vecb and vecv=veca x vecb then vecv is

If veca,vecb,vecc and vecd are unit vectors such that (vecaxxvecb).(veccxxvecd)=1 and veca.vecc=1/2 then (A) veca,vecb,vecc are non coplanar (B) vecb,vecc, vecd are non coplanar (C) vecb, vecd are non paralel (D) veca, vecd are paralel and vecb, vecc are parallel

If |veca+vecb|=|veca-vecb| , then what is the angle between veca " and "vecb ?
