Question

The figure below shows four small spheres, each with a positive charge, at the corners of a square. The length of each side of the square is a. The sphere at top-right has a charge of q; the one at lower-left has a charge of 2.0q; the other two each have a charge of 5.0q. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) 2.0q5.0q5.0q Four positive charges are organized in a square configuration, with one charge at each vertex of the square. Each side of the square has length a. The upper left corner is labeled 5.0q, the upper right corner is labeled q, the lower right corner is labeled 5.0q, and the lower left corner is labeled 2.0q. (a) What is the magnitude of the force on the sphere with charge q? Express your answer in terms of ke, q, and a in symbolic form.
