Need help using Coulomb's Law; finding q1 when q2>q1

[Michael126]

A system consists of two positive point charges, q_1 and q_2 > q_1. The total charge of the system is 64.0 \mu C, and elec each charge experiences antrostatic force of magnitude 76.0 N when the separation between them is 0.270 {\rm m}.

Im having a little trouble determining q1, it must be simple but i just can't see it! arrgh!

 

[Michael126]

the equation used is coulombs law; f= k *q1*q2/ r squared

You have a system of two equations and two unknowns. The unknowns are q1 and q2. One equation is Coulomb's Law as you have written it in posting #2. What is the second equation?

I realize i should post my work that I've done already...well i decided that both q1 and q2 cannot be equal since all other info would be irrelevant..i tried using the fundamental charge, 1.6*10^-19 as the value for q1 but that doesn't seem to fit, I've been on this problem for about an hour now but i can't seem to see the relation between the two..i apologize about my original post that didnt include my thinking process

i'm not sure we were given a second equation in lecture...maybe that's why I am not understanding haha

The second equation is stated in the problem. Read the problem statement carefully.

I just got it man, thank you!
