I’m pretty confident that the magnitude should be more than 5, but I can't recall if it’s closer to 7 or 9.

I feel like I might have messed up the calculation last time. Is it possible the answer could be 5.92?

I remember practicing a similar question, and I think the answer was around 7.00, but I'm not entirely sure.

I think the magnitude is calculated using the square root of the sum of the squares of the components, right?
