(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Let vector E = (10 i + 1 j) and vector F = (5 i - 5 j). Find the magnitude of F

2. Relevant equations

I thought it would just be 5^2 - 5^2 which equals 25-25, all square rooted.

3. The attempt at a solution

I keep getting 0 but it's not right. Help?
