Question

if the angle between two collinear vector is pi radians, vectors are said to be​

Answer 1

Answer ⇒ Antiparallel Vectors.

Explanation ⇒ First of all, what is vector ?

A vector is a Physical quantity that has both magnitude and direction.

Vectors are parallel if they have the same direction.

Both components of one vector must be in the same ratio to the corresponding components of the parallel vector.

''Those vectors which have an angle equal to zero degree are regarded as the parallel vectors.''

When the angle changes from zero degree to 180 degree, the direction of both the vectors becomes reversed.

Hence, both are said to be anti-parallel.

Hope it helps.

Answer 2

Vectors are parallel if they have the same direction. Both components of one vector must be in the same ratio to the corresponding components of the parallel vector. ''Those vectors which have an angle equal to zero degree are regarded as the parallel vectors. ... Hence, both are said to be anti-parallel. ❤️
