The point charges in the figure below are located at the corners of an equilateral triangle 25.0 cm on a side, where qa 9b (a) Find the electric field at the location of qa magnitude direction N/C (counterclockwise from the +x-axis) (b) What is the force on q, given that q = +1.50 nC? magnitude direction N (counterclockwise from the +x-axis) = +28.0 C and -4.70 C. (Assume that the +x-axis is directed to the right.)
