Two point charges q and 4q are at a distance l from each other.

Which charge and at what distance must be introduce into the system from the first charge so the entire system is in equilibrium? Will it be a stable or unstable equilibrium?

I am having problem understanding this problem so a clear explanation would be a great help!

Thank you so much!
