A thin, fixed rod is 30.0mm long and carries a total positive charge of 100.0nC distributed uniformly along its length. A single small positive point charge, Q=2.0 μC, is placed 180.0mm from the left end of the charged rod in a direction along the line of the rod. What is the total electrical force on the charge Q? Sign convention - if the force points left, enter it as negative, right as postive.
