Question

5) Which of the following represents the correct form of vector Ā written in terms of
predefined rectangular unit vectors:​

Answer 1

Answer:

As unit vector is a vector having magnitude of 1. As per this option, if magnitude of this vector is find out it comes out to be 1. So, | i + j | /√2 = 1. Hence, this vector have magnitude of 1 unit, so it's a unit vector.

Explanation:

The base vectors of a rectangular coordinate system are given by a set of three mutually orthogonal unit vectors denoted by , , and that are along the x, y, and z coordinate directions, respectively, as shown in the figure.
