Magnitude of the electric field problem

[indpa7]

Hey guys, I'm having a trouble solving this problem. The question is: A positive charge Q= 1.1 x 10^-11 Coulombs is located 10^-2 meters away from a negative charge of equal magnitude. Point P is exactly between them. What is the magnitude of the electric field at Point P?

2kq/(r^2)......k is the constant, q is charge, r is the distance from p to one of the charged
