Two identical teflon rods are 10 centimeters long and rubbed with fur so that they each have a total negative charge of 20 microCoulombs that is uniformly distributed along their length. They are arranged along the same axis, with their ends 5 centimeters apart. What is the magnitude of the electrostatic force felt by each rod in Newtons?

assume all the charge is at the center on each rod. F=kQQ/distancefromcenters^2
