A charge Q1=7μC is located at the origin and a second charge Q2=-5 μC is located on the x-axis, 0.3m from the origin as shown in the figure. Find the electric field at the point P which has coordinates ( 0 , 0.4 ). Given k=9x109 SI.

Note: (To determine the resultant electric field find the x and y component for E and then determine the resultant E).
