A question about electric charge?
Question : http://postimg.org/image/g1y6ko6aj/

I am bad at Physics. I have no idea how to do it even though I have studied my lecture notes. Can anyone help me with detailed explanation?
I want know if qb = qa or the force (blue arrow) is equal to the force(red arrow), and why?
