Question

Consider the figure (a square) given below

Based on above figure, which of the following is true?

• A. $a$ and $d$ are coinitial vectors
• B. $b$ and $d$ are coinitial vectors
• C. $a$ and $c$ are equal vectors
• D. None of the above

Answer 1

Answer: (A)

(i) Vectors a and d are coinitial because they have the same initial point.

(ii) Vectors $b$ and $d$ are not coinitial vectors.
(iii) Vectors a and $c$ are collinear but not equal. Although they are parallel, this is because their directions are not same.
