While delivering a lecture on vectors Phusics teacher told the students about zero vector or mnll vector, i.e. a vector which has zero magnitude and arbitray direction. It is represented by vec 0 (arrow ovet the numnet zero . The students wer baffled. Read the above passage and answer the following questins : (i) What was the becessity of the concept zero vector ? ltbRgt Give any one illustravion of zero vector. (ii) What is the phusical significane of zero vector ?

When is the sum of two non zero vectors is zero ?

The cross product of two vectors gives a vector perpendicular to the plane containing the vectors. If vec(a) and vec(b) are non-zero vectors, then vec(a)*(vec(a)xxvec(b))= _________

Two statements are made regarding three non-zero vectors vecA, vecB and vec C having different magnitudes : (1) Any two of these vectors can be combined to give a zero vector. (2) The three vectors can be combined to give a zero vector. Then,
