Question
Find the magnitude of the vector $ \| \vec{v} \| = \left(12,~0\right) $ .
Answer
The magnitude of vector $ \vec{v} $ is $ \| \vec{v} \| = 12 $ .
Explanation
To find magnitude of a vector $ v=(a,b) $ we use formula $ ||v|| = \sqrt{a^2+b^2} $
In this example $ a = 12 $ and $ b = 0 $, so:
$$ ||v|| = \sqrt{ 12^2 + 0^2 } = \sqrt{ 144 + 0 } = \sqrt{ 144 } = 12$$This page was created using
