Hello !Ankit jha
Assume -Q is charge placed at centre of square which keeps system in equilibrium.Find total electrostatic force at centre due to 4 charges at corner and charge -Q.Now add vectorially all forces and equate to zero as system should be in equilibrium as per as questions.This expressions will give value of charge Q.
Hints:Length of daignol is (2½a).Charge will placed at length ( a/2½) from corner of square.where a is length of side of square.
You can ask if you have any other queries.
GOOD LUCK!
