Electric field strength

Physics Problem , please help I’m writing a test tomorrow and want to know if I’m right.
The Question :

Two point charges Q1 and Q2 are spaced 3m apart.

Q1’s charge = 14C
Q2’s charge = +20 C

*Q1 ——-(3meters)——- *Q2 —-(2meters)—- *P

Calculate the net electric field at point P, 2m right from where Q2 is situated?

My Calculations :

Q1 on P = -5.04 x10^9
Q2 on P = 4.5 x10^10

Final answer = Net : 3.996×10^10

Formula used:

E = (k*Q)/r^2
