Question

a)
Define unit vector and zero vector​

Answer 1

Answer:

unit vector is that which has magnitude of one and zero vector is that which has magnitude of zero

Answer 2

Explanation:

1)zero vector=A vector having zero magnitude or zero amount with a particular direction is called zero vector.

for example, acceleration of object moving with uniform velocity

2)unit vector=unit vector are those which have unit magnitude in a given direction .

means unit vector shows direction of particular vector
