Question

Identify the unit vector in the following.

• A. Umesh Nagarale-148276421
• B. Lenesh Nagarale-148276421
• C. Dinesh Nepaale-148276421
• D. Lenesh Nagarale-145276421

Answer 1

The question cannot be answered from the provided options because they are not valid vector expressions.

Answer 2

A unit vector is a vector whose magnitude (or length) is exactly one. It is used to indicate a direction. If a vector is represented as $\vec{A} = A_x \hat{i} + A_y \hat{j} + A_z \hat{k}$ in Cartesian coordinates, its magnitude is calculated using the formula:

$|\vec{A}| = \sqrt{A_x^2 + A_y^2 + A_z^2}$

For a vector to be a unit vector, its magnitude, $|\vec{A}|$, must be equal to 1. The options provided are not mathematical vector expressions, therefore it is impossible to identify a unit vector.
