`veca and vecb` are two non collinear vectors then `xveca+yvecb` (where x and y are scalars) represents a vector which is (A) parallel to vecb` (B) `parallel to `veca` (C) coplanar with `veca and vecb` (D) none of these

If veca and vecb are non - zero vectors such that |veca + vecb| = |veca - 2vecb| then

If veca and vecb are two non collinear unit vectors and |veca+vecb|= sqrt3 , then find the value of (veca- vecb)*(2veca+ vecb)

If veca and vecb are two non collinear unit vectors and iveca+vecbi=sqrt(3) then find the value of (veca-vecb).(2veca+vecb)

If veca and vecb be two non collinear vectors such that veca=vecc+vecd , where vecc is parallel to vecb and vecd is perpendicular to vecb obtain expression for vecc and vecd in terms of veca and vecb as: vecd= veca- ((veca.vecb)vecb)/b^2,vecc= ((veca.vecb)vecb)/b^2

If veca,vecb,vecc are any thre vectors then (vecaxxvecb)xxvecc is a vector (A) perpendicular to vecaxxvecb (B) coplanar with veca and vecb (C) parallel to vecc (D) parallel to either veca or vecb

Let veca and vecb be two non-collinear unit vectors. If vecu=veca-(veca.vecb)vecb and vec=vecaxxvecb , then |vecv| is

If vectors veca and vecb are non collinear then veca/(|veca|)+vecb/(|vecb|) is (A) a unit vector in the plane of veca and vecb (B) in the plane of veca and vecb (C) equally inclined ot vecas and vecb (D) perpendiculat to veca xx vecb

If veca and vecb are two unit vectors, then the vector (veca+vecb)xx(vecaxxvecb) is parallel to the vector

If veca, vecb and vecc 1 are three non-coplanar vectors, then (veca + vecb + vecc). [(veca + vecb) xx (veca + vecc)] equals

If veca, vecb and vecc 1 are three non-coplanar vectors, then (veca + vecb + vecc). [(veca + vecb) xx (veca + vecc)] equals
