Coulomb's law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance d is
|F|= K(|QQ'|/d2),
Where K = (1/ 4 Πε0), and ε0 = 8.854 x 10-12 C2/(Nm2) is permittivity of free space.
Consider two point charges located on the x axis: one charge q1 = -18.0 nC is located at x1 = -1.670m; the second charge q2 = 33.0 nC is at the origin (x = 0.0000).
What is the net force exerted by these two charges on a third charge q3 = 49.5 nC placed between q1 and q2 at x3 = -1.195m?
