" For the system shown in figure find "Q" for which resultant force on "q" is zero."

For the system in figure find Q for which resultant force on q is zero.

For the system shown below, the value of Q for which resultant force on q is zero is

The opposite corners of square carry Q charges each and the other two opposite corners of the same square carry q charges each. If the resultant force on q is zero , how are Q and q related?
