| Answer» VECTORS which are of equal magnitude and same direction are SAID to be 1) equal vector .More terminology related to vectors :- a) parallel Vectors :- Vector having same direction are called parallel vector.b) Anti parallel Vectors :- Vector having opposite direction aee called Anti-parallel vector.c) Co-INITIAL vectors :- Vector having same initial point are called co-initial vectors. They are also known as concurrent vectorsd) Co-terminus vectors :- Vector having same TERMINAL point are called co-terminal vectors.e) Unit vector :- A vector having magnitude equal to one is called unit vector.f) Zero vector or null vector :- They have zero magnitude.g) Orthogonal vectors :- Perpendicular vectors are called orthogonal vectors.h) Coplanar vectors :- Vector LYING in the same plane are called coplanar vector. | |
