Collinear and coplanar vectors

Answer the following as true or flase: vec a and vec b are collinear.Two collinear vectors are always equal in magnitude.Zero vector is unique.Two vectors having same magnitude are collinear.Two collinear vectors having the same magnitude are equal.

Theorem 1: If a and b are two non collinear vectors; then every vector r coplanar with a and b can be expressed in one and only one way as a linear combination: xa+yb.

What are coplanar vectors ?

Answer the following as true or false.( i ) vec a and and are collinear.(ii) Two collinear vectors are always equal in magnitude.(iii) Two vectors collinear vectors having the same magnitude collinear vectors having the same magnitude are equal.

If vecA,vecB and vecC are coplanar vectors, then

If the angle between two collinear vector is pi radians, vector are said to be _______

Explain (i) Unit vector (ii) Equal vectors (iii) Negative vectors, (iv) Coinitial v ectors (v) Collinear vectors and (vi) Copanar vectors.
