In Figure particle 1 of charge ?? 80.0C and particle 2 of charge + 40.0C are held

In Figure particle 1 of charge ?? 80.0μC and particle 2 of charge + 40.0μC 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 = 20.0μC, if particle 3 is placed at

(a) x = 40.0 cm and

(b) x = 80.0 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?
