1.	If oversettoA+oversettoB=oversettoA-oversettoB, what can you say about B? Give two physical examples of such vectors.
Answer» Solution :`oversettoA+oversettoB=oversettoA-oversettoB,`when is a NULL VECTOR. The acceleration vector of an object moving with uniform VELOCITY, the velocity vector of a STATIONARY object are examples of a null vector.
