Two charges Q1 = -1 μC and Q2 = +1 μC are located on the y-axis at y1 = +1 cm and y2 = -1 cm respectively?
A third charge Q3 = +8 μC is added on the y-axis so that the electric field at the origin is equal to zero. What is the position of Q3?

At the origin, the field due to the two charges Q1 and Q2 is acting upward.
To nullify the field the charge Q3 must be above the charge Q1.
8.e-6 / y² = 2*1.e-6/1
8 / y² = 2 cm from the origin above the charge Q1

a million Corinthians a million:27-28 27But God hath chosen the silly problems with the international to confound the clever; and God hath chosen the susceptible problems with the international to confound the flaws that are powerful; 28And base problems with the international, and issues that are despised, hath God chosen, yea, and issues that are no longer, to convey to nought issues that are: those 2 verses clarify verse 25. God can cut back Himself and He can choose for all individuals He desires to confront this international. bear in mind whilst Adam and Eve sin interior the backyard? He asked Adam, why are you hiding. God already knew Adam had sin. So what verse 25 is asserting is that the foolishness of God is wiser then adult adult males. Like interior the backyard God now and back seems to be proscribing Himself whilst fairly He is conscious all issues. So now and back whilst he cut back Himself it rather is counted wiser then any adult adult males. Did you recognize me?
