Three positive charges are located in the x-y plane (see plot below), with Q1=3.10 μC, Q2=5.20 μC and Q3=6.30 μC. Note that the charges are located at grid intersections, and that the x and y coordinates are in cm.

A. Calculate the magnitude of the electric force on Q1 due to Q2.
The Attempt at a Solution
Then for the magnitude: sqrt((160.977)^2+(90.54)^2))
Thank you in advance because I really cannot figure out what I'm doing wrong.
