Now we will consider a two-dimensional arrangement of charges. a point charge q1=2.0μc is located on the positive y-axis at y=0.30m, and an identical charge q2 is at the origin. find the magnitude and direction of the total force that these two charges exert on a third charge q3=4.0μc that is on the positive x-axis at x=0.40m. what is the magnitude of the net force on q3 if q1=2.0μc, as in the example, but q2=−3.0μc? express your answer in newtons to two significant figures. what is the direction of the force on q3 if q1=2.0μc, as in the example, but q2=−3.0μc? express your answer in degrees below the −x axis as an integer.
