[QUOTE="Ch3m_, post: 5477680, member: 571256"] [h2]Homework Statement [/h2] A +1.0 μC charge is placed at point X. A +4.0 μC charge is placed at point Y, 50 cm from X. How far from X, on the line XY, is the point where the electric field strength is zero? [h2]Homework Equations[/h2] E = Q/4πε[B][SUB][/SUB][/B][SUB]0[B][/B][/SUB][B][/B]r[SUP]2[/SUP] [h2]The Attempt at a Solution[/h2] I know that the electric field is zero at the point where the magnitude of the field due to the 1.0 μC charge is equal to the magnitude of the field due to the 4.0 μC charge, but I have tried making the equations equal to each other and don't know how to find r [/QUOTE]
