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

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.
