Along a number line, there exist 2 charged objects. At x = 8 m,there is a 4 nC charge (Q1), and at x = -5 m, there is a -9 nCcharge (Q2). What is the electric field at x = 0 m? What is theelectric potential at x = 0 m? If a third charge (Q3 = 1.6190 nC)were place on the number line so that it was in equilibrium, wherewould it be placed? Given the position of Q3 found in the previousproblem, what is the total force, stack text F end text withrightwards harpoon with barb upwards on top, on Q1?
