Question

Which amongst the following is true for like vectors?

• A. Like vectors are those vectors which have the same direction irrespective of their magnitudes.
• B. Like vectors are those vectors which have the same magnitude irrespective of their directions
• C. Like vectors are those vectors which have the same magnitude as well as the directions
• D. None of the above

Answer 1

The correct option is A Like vectors are those vectors which have the same direction irrespective of their magnitudes.

like vector can be defined by parallel vector

$\overrightarrow{a}=\lambda \overrightarrow{b}$----------(1)

Here if the anglr between both vector is not $180$ then it is like vector and if the angle between them is $180$ then it is unlike vector

from eq $\left(1\right)$ it is very clear that the magnitude of both vector is not equal but the direction is same because it is parallel vector
