Hello all. I am kindof stuck on this problem. It asks: The figure below shows three point charges all posotive. If the net electric force on the center charge is zero, what is the value of y/x.(adsbygoogle = window.adsbygoogle || []).push({});

The answers:

a) 4/9

b) [tex] \sqrt{2/3} [/tex]

c) [tex] \sqrt{3/2} [/tex]

d) 3/2

e) 9/4

This is my figuring:

[tex] K\frac{2q}{x^2} - K\frac{3q}{y^2} = 0 [/tex]

But how can I get an actual number without a value for q?

Thanks

Chris
