Question

6. Which among the following is needed to specify a vector quantity other than magnitude.

a) amplitude b)direction
c) both a and b c) none of this​

Answer 1

Vector quantity is one which has magnitude and direction. So option b

Answer 2

B) Direction

• Vector is a quantity in physics that has both magnitude and direction.

• It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to its magnitude.

• Vector doesn't have a position. As its length is not changed, a vector is not altered if it is displaced parallel to itself
