Forces in a Three-Charge System Coulomb's law for the magnitude of the force between two particles with charges and separated by a distance is , where , and is the permittivity of free space. Consider two point charges located on the x axis: one charge, = -16.0 , is located at = -1.710 ; the second charge, = 32.0 , is at the origin . Part A What is the net force exerted by these two charges on a third charge = 55.0 placed between and at = -1.140 ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures.
