A figure shows a dot located at a distance r from the horizontal line connecting two charges. The horizontal distance between the dot and each charge is r. The dot is above the line connecting two charges. The left charge is positive and is 3.0 nC. The right charge is also positive and is also 3.0 nC. Let r=4.7 cm. What is the strngth of the electric field at the position indicated by the dot in the figure? What is the direction of the electric field at the position indicated by the dot in the figure? Specify the direction as an angle measured clockwise from the positive y axis
