= : 0) and Two charges +7 C and +15 are placed along the x axis, with the first charge at the origin (x the second charge at x = = +1 m. Find the magnitude and direction of the net force on a -5 nC charge when placed at the following locations below. Overall Hint a. halfway between the two charges: magnitude of force is -4.284 direction is in +x direction b. on the x axis at x = -0.5 m: magnitude of force is is in +x direction XmN, and the mN, and the direction c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +15 C charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) Magnitude of force is degrees below -x axis. mN, and the direction is
