Four charges of magnitude +q are placed at the corners of a square whose sides have a length d. What is the magnitude if the total force exerted by the four charges on a charge Q located a distance b along a line perpendicular to the plane of the square and equidistant from the four charges?
The result of my attempt was:
F= 4kqQb/((d^2/2)+b^2)^3/2
but I don't know if is
F= kqQb/(b^2+l^2/2)^(3/2)
