Thread: net electric field.

Two charges are located on the x axis:

q1 = +4.0 µC at x1 = +4.0 cm, and q2 = +4.0 µC at x2 = -4.0 cm.

Two other charges are located on the y axis: q3 = +4.0 µC at y3 = +5.0 cm, and q4 = -7.0 µC at y4 = +7.0 cm.

Find the net electric field (magnitude and direction) at the origin.

magnitude in N/C
and the direction ° (measured counter clockwise from the x axis)

not sure how to use the x and y axis Coloumb to help.

The x,y axes are used in the problem to tell u the distance of each charge to the origin.

Now you have to find the electrical field generated by each charge at the origin, and then do a vector sum.
