Three point charges are fixed in place in a right triangle, as shown in the figure. What is the magnitude of the electric force on the +1.00-C charge due to the other two charges?
What angle does the force make with the -x-axis? A positive angle is counterclockwise from the -x-axis.

If y gets smaller as x gets bigger and y have an relationship?
