Trying to work this one out.(adsbygoogle = window.adsbygoogle || []).push({});

If you have two charges Q1 and Q2 separated by a distance of x then how do you show what distance from the charge Q1 is the total electric from the two charges zero.

I know that Enet =E1 +E2 and if i use coulombs law i get:

KQ1/x^2 +KQ2/x^2

the K cancles and you get Q1/x^2 + Q2/x^2 = 0 but that doest seeem right. anyone with any ideas?
