Show that the points `veca+2vecb+3c-2veca+3vecb+5vecc and 7veca-vecc` are colinear.

Show that the vectors veca-2vecb+3vecc,-2veca+3vecb-4vecc and - vecb+2vecc are coplanar vector where veca, vecb, vecc are non coplanar vectors

Show that the vectors 2veca-vecb+3vecc, veca+vecb-2vecc and veca+vecb-3vecc are non-coplanar vectors (where veca, vecb, vecc are non-coplanar vectors).

If veca, vecb and vecc are non-coplanar vectors, prove that the four points 2veca+3vecb-vecc, veca-2vecb+3vecc, 3veca+4vecb-2vecc and veca-6vecb+ 6 vecc are coplanar.

Show that the three points whose position vectors are veca-2vecb+3vecc, 2veca+3vecb-4vecc, -7vecb+10vecc are collinear

Prove that the four points 2veca+3vecb-vecc, veca-2vecb+3vecc,3veca+4vecb-2vecc and veca-6vecb+6vecc are coplanar where veca,vecb,vecc are non-coplanar vectors

Show that the points having position vectors (veca-2vecb+3vecc),(-2veca+3vecb+2vecc),(-8veca+13vecb) re collinear whatever veca,vecb,vecc may be

If veca, vecb and vecc are three non-zero vectors, no two of which are collinear, veca +2 vecb is collinear with vecc and vecb + 3 vecc is collinear with veca , then find the value of |veca + 2vecb + 6vecc| .

Let veca,vecb, and vecc be three non zero vector such that no two of these are collinear. If the vector veca+2vecb is collinear with vecc and vecb+3vecc is colinear with veca (lamda being some non zero scalar) then veca\+2vecb+6vecc equals (A) lamdaveca (B) lamdavecb (C) lamdavecc (D) 0

Examine whather followig vectors are coplanar or nto: veca+vecb-vecc, veca-3vecb+vecc nd 2veca-vecb-vecc

The line joining the points 6veca-4vecb+4vecc, -4vecc and the line joining the points -veca-2vecb-3vecc, veca+2vecb-5vecc intersect at
