Chapter 8.1, Problem 36E

To determine

To describe: the significance of diagonal for the given situation.

Answer to Problem 36E

It represents the magnitude of the sum of two vectors.

Explanation of Solution

Given information:

The significance of diagonal between the terminal points of the vector in a parallelogram method.

Calculation:

Let’s draw a vector by parallelogram method for $\overrightarrow{u}\text{ and }\overrightarrow{v}$ .

The diagonal between the terminal points of the vector in a parallelogram method always represents the sum of two vectors i.e. $\overrightarrow{u}\text{ + }\overrightarrow{v}$ .
