Question

When are two vectors collinear?

Options

• Their corresponding components are equal.

• Their magnitudes are equal.

• One is a scalar multiple of the other, \[\vec{b}=\lambda\vec{a}\].

• Their \[\hat{k}\] components are equal.

Answer 1

Two vectors are collinear if one vector is a scalar multiple of the other. This relationship is written as \[\vec{b}=\lambda\vec{a}\].
