Question

If `veca` and `vecb` are two collinear vectors then which of the following are incorrect.

पर्याय

• `vecb = lambdaveca` for some scalar

• `veca = +- vecb`

• the respective components of `veca` and `vecb` are proportional

• both vectors `veca` and `vecb` have some direction but different magnitude.

Answer 1

both vectors `veca` and `vecb` have some direction but different magnitude.

Explanation:

Because the vectors `veca` and `vecb` are collinear, they are not necessarily in the same direction. They could be going in opposite directions. Their magnitudes may different.
