Two charges are placed on the x-axis: +3μC is at x=0 and -5μC is at x=0.80m. Where must a third charge Q be placed if the force it experiences is to be zero? Do not forget to draw the FBD of the third charge illustrating its relationship with the two charges.

Two charges, 91 and 92, are located at the origin and at (0.50 m, 0), respectively. Where on the x-axis must a third charge, 93, of arbitrary sign be placed to be in elec-trostatic equilibrium if (a) 91 and 92 are like charges of equal magnitude,  (b) 91 and 92 are unlike charges of equal magnitude, and (c) 91 +3.0 uC and92 = -7.0 μC? ?

Two positive charges on the y-axis are located at a distance a = 14 cm from the origin. The charge of each of them is q = 1 μC or -1 μC Another positive point charge, with charge Q = 99 μC, is located at point P on the positive x-axis a distance b = 1.1 m from the origin. Calculate the x component of the net force, in Newtons, acting on the point charge at P.

Two charges +10 μC and +6 μC are placed along the x axis, with the first charge at the origin (x = 0) and the second charge at x = +1 m. Find the magnitude and direction of the net force on a -6 nC charge when placed at the following locations below. Overall Hint a. halfway between the two charges: magnitude of force is direction is Select an answer b. on the axis at x = -0.5 m: magnitude of force is Magnitude of force is degrees below -x axis. mN, and the is Select an answer c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +6 μC charge in a direction perpendicular to the line joining the two fixed charges): Hint for (c) mN, and the direction is mN, and the direction
