Coulomb's law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance d is where K = = |F| = K- 1 -12 08.854 x 10 C/(N m) is the permittivity of free space. |QQ'| d " and Consider two point charges located on the x axis: one charge, 91 = -18.5 nC, is located at 1 = -1.740 m; the second charge, 92 = 40.0 nC, is at the origin (x = : 0). Part A What is (Fnet 3), the x-component of the net force exerted by these two charges on a thi charge q3 = 50.0 nC placed between 9 and 92 at x3 = -1.175 m ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures. View Available Hint(s) VE (Fnet 3) r = www ?
