Five Particles Are Shot from the Left into a Region

Five particles are shot from the left into a region that contains a uniform electric field. The numbered lines show the paths taken by the five particles. A negatively charged particle with a charge -3Q follows path 2 while it moves through this field. Do not consider any effects due to gravity.
-What is the magnitude of the electric field due to a 6.0 × 10^-9 C charge at a point located 0.025 m from the charge?

A) 8.6 × 10² N/C
B) 1.2 × 10⁴ N/C
C) 1.8 × 10⁵ N/C
D) 3.6 × 10⁶ N/C
E) 7.2 × 10⁷ N/C
