as zero vector



RESULTANT VECTOR - Correct answers✔✔The relustant of two or more vectors is defined as
that single vector, which produces the same effect as produced by all the vectors together



NEGATIVE VECTOR - Correct answers✔✔A negative vector of the given vector is a vector of
the smae magnitude but opposite in direction to that of the guven vector



EQUAL VECTORS - Correct answers✔✔Two vectors A and B representing same physical
quantity are said to be equal is and only if they have same magnitude and direction



POSITION VECTOR - Correct answers✔✔A vector that gives the position of a particle at a
point with respect to the origin of chosen co-ordinate system



Unit vector - Correct answers✔✔A vector having unit magnitude in a given direction is called a
unit vector in that direction.



Vector product of two vectors - Correct answers✔✔The vector product of two vectors is the third
vector whose magnitude is equal to the product of the magnitude of the two vectors and sine of
smaller angel between them
