Three positive charges are located in the x-y plane (see plot below), with Q1=3.10 ?C, Q2=5.20 ?C and Q3=6.30 ?C. Note that the charges are located at grid intersections, and that the x and y coordinates are in cm.
1. Compute the magnitude of the electric force on Q3 due to Q1.
2. Compute the y-component of the force on Q3 due to Q2.
