When a third charge is placed at the origin, it is found that the force on it is zero. Find alpha?

Two charges Q and 5Q are located as shown in the figure below.

If possible, please show work so i can learn how to do it. Thanks!

2. Relevant equations

3. The attempt at a solution

I know that force varies as a function of charge and inversely proportional to square of distance.

So i need to use this equation somehow:

F = k Qa Qb / d^2
