In Fig. 21-25, particle 1 of charge -SO.O f.J.,C and particle 2 of charge +40.0 f.J.,C are held at separation L = 20.0 cm on an x axis. In unit-vector notation, what is the net electrostatic force on particle 3, of charge q3 = 20.0 f.J.,C, if particle 3 is placed at (a) x = 40.0 cm and (b) x = SO.O cm? What should be the (c) x and (d) Y coordinates of particle 3 if the net electrostatic force on it due to particles 1 and 2 is zero?
