There are four point charges that have equal magnitudes in a line. There are 3 positive ones and one negative one placed like this
+ + + -
They are fixed in place on a straight line, and adjacent charges are equally separated by a distance d. Consider the net electrostatic force acting on each charge. Calculate the ratio of the largest to the smallest net force.
The professor teaching this summer is new and I don't understand him that well! I'm telling to learn on my own now by doing problems! Short explanation and numerical answer needed! Thanks!!!!!
