Chapter 3: Q. 7 (page 77)

Can a vector have zero magnitudes if one of its components is nonzero? Explain.

Short Answer

Expert verified

It is not possible to have a vector of zero magnitude when one of its components is non-zero.

Step by step solution

01

Step 1. Given information

A vector of zero magnitude is nothing but zero vector. If a vector R鈫�is inclined by an angle 胃 with respect to x-axis then x-component of is Rcos胃 and its y- component isRsin胃 .

02

Step 2. Explanation

If vector R鈫� is a zero vector, then its magnitude R = 0 . It means that both of its components Rcos胃 andRsin胃 terms should be equal to zero.

| The treasure map in FIGURE P3.40 gives the following directions to the buried treasure: "Start at the old oak tree, walk due north for 500 paces, then due east for 100 paces. Dig." But when you arrive, you find an angry dragon just north of the tree. To avoid the dragon, you set off along the yellow brick road at an angle east of north. After walking 300 paces you see an opening through the woods. Which direction should you go, and how far, to reach the treasure?
