Three point charges of 2.00 ?C, 7.00 ?C, and -4.00 ?C are located at the corners of an equilateral triangle as shown. The two on the x-axis are in fixed positions.

1.Draw a free-body diagram to show the electric forces exerting on the 7.00- ?C charge and clearly indicate what object exerts each electric force on it.

2. Set up the x -axis horizontally, the y -axis vertically, and the origin placed at the location of the 7.00- ?C charge. Project all the electric forces on x and y axes. Calculate the x and y components of each electric force.

3. Calculate the net electric forces in both x and y directions.

4. Calculate the total net electric force on the 7.00- ?C charge.
