Hey guys! I'm new here and I need some help with an exercise about electricity (electrostatics). I've tried to solve it but I can't figure out how to do it... I'm going to translate the exercise because I have it in Spanish, hehe... Thanks a lot. :)

Two point charges, 5 μC and -10 μC, are 1 m apart. Where, in the line joining the two charges, the electric field is equal to zero?

How could I know where the electric field is going to be?

1 meter is a very long distance when your talking about charges"with a Microcoloumb unit " but any way..i think  as the -ve charge is double higher in magnitude, so all the Electric field that comes out from the +ve charge will be sucked in by the -ve charge , so there will be no place in between the 2 charges that you gone find the E-field = Zero...
