Chapter 3: Q. 3 (page 77)

If $\overset{鈫�}{C} = \overset{鈫�}{A} + \overset{鈫�}{B},$ Can $C = 0 ?$ Can $C < 0 ?$ For each, show how or explain why not.

Short Answer

Expert verified

The magnitude of vector $C$ can be $0$ but it magnitude $C$ canot be less than $0 .$

Step by step solution

Step 1. Given information

It is given that $\overset{鈫�}{C} = \overset{鈫�}{A} + \overset{鈫�}{B} .$ We need to write can $C = 0$ and can $C < 0 .$ For each we need to showhow or explain why not.

Step 2. Explanation

Length of a vector,

A vector either has length, or it has not. Its magnitude cannot be negative.

$C$ can be $0$ if $\overset{鈫�}{A} = - \overset{鈫�}{B},$ in which case the sum $\overset{鈫�}{C}$ is a vector of length $0 .$

Step 3. Explanation

The magnitude of a vector is always positive so the magnitude of vector $\overset{鈫�}{C}$ can't be negative.
