Learning Goal: To practice Problem$-$Solving Strategy $17\mathrm{.}1$ Coulomb's Law Two charges are fixed on the x axis: one with a charge of q$1=5\mathrm{.}00$ C at x$1=-1\mathrm{.}00$ mm and the other with a charge of q$2=3\mathrm{.}00$ C at x$2=1\mathrm{.}50$ m $.$ Find the force F exerted on a charge q $=-5\mathrm{.}00$ C placed at the origin $($x$=0).$ Part B Which of the following gives the proper directions for the forces on charge qq due to charges q$1$q$1$ and q$2$q$2?$ F$1$F$1$ is the force on charge qq due to charge q$1$q$1,$ and F$2$F$2$ is the force on charge qq due to charge q$2$q$2.$ Standard coordinates are being used $($i$.$e$.,$ "left" is the negative x direction, and "right" is the positive x direction$).$
