###### Question details

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.

A) In the same example, what is the magnitude of the net force on q3 if q1=2.0μC, as in the example, but q2=−2.0μC? Express your answer in newtons to two significant figures.

B) In the same example, what is the direction of the force on q3 if q1=2.0μC, as in the example, but q2=−2.0μC? Express your answer in degrees below the −x axis as an integer.
