Question

In the figure given below, which vectors are coinitial but not equal?

(a) \(\vec{a}\), \(\vec{b}\) and \(\vec{c}\)

(b) \(\vec{b}\) and \(\vec{c}\)

(c) \(\vec{a}\) and \(\vec{b}\)

(d) \(\vec{a}\) and \(\vec{c}\)

I got this question by my college director while I was bunking the class.

I'd like to ask this question from Types of Vectors in division Vector Algebra of Mathematics – Class 12

Answer 1

Correct choice is (d) \(\vec{a}\) and \(\vec{c}\)

The best I can explain: The vectors which start from the same initial point are called coinitial vectors. In the given figure, vectors \(\vec{a}\) and \(\vec{c}\) start from the same point but are of different magnitude. Therefore, vectors \(\vec{a}\) and \(\vec{c}\) ae coinitial but not equal.
