QUESTION
Two particles are fixed to an x-axis: particle 1 of charge q1 =2.1x108 C at x=20cm and particle 2 of charge q2 = 4.00 q1 at x = 70 cm.
Two particles are fixed to an x-axis: particle 1 of charge q1 =2.1x10‒8 C at x=20cm and particle 2 of charge q2 = ‒ 4.00 q1 at x = 70 cm. At what coordinate on the x axis is the net electric field produced by the particles equal to zero?
