Point charges are located at the corners of a rectangle in the first quadrant: q1=+3μC at O(0,0), q2=−4μC at P(5cm,0) and q3=+2μC at Q(0,4cm). A test charge q=+1μC is placed at R(5cm,4cm).
a. (i) Calculate the x-component of the net force on the test charge.
b. (ii) Calculate the y-component of the net force on the test charge.
c. (iii) Determine the magnitude of the net force on the test charge.
