Question

Which of the following is used to represent the magnitude of vector \(\vec{A}\)?

(a) \(\hat{A}\)

(b) |\(\vec{A}\)|

(c) \(\underset{A}{\leftrightarrow}\)

(d) \(\vec{A}\)

I had been asked this question in homework.

My question is taken from Vector Algebra Basics in section Vector Algebra of Mathematics – Class 12

Answer 1

The correct answer is (b) |\(\vec{A}\)|

Easy explanation: The correct way of representing the magnitude of a given vector A is|\(\vec{A}\)|. The magnitude of a vector is the distance between the initial and the terminal points of a vector.
