Two particles are in a uniform electric field that points in the 1x direction and has a magnitude of 2500 N/C. The mass and charge of particle 1 are m1 = 1.4 x 10-5 kg and q1 = -7.0 µC, while the corresponding values for particle 2 are m2 = 2.6 × 10-5 kg and q2 = +18 µC. Initially the particles are at rest. The particles are both located on the same electric field line but are separated from each other by a distance d. Particle 1 is located to the left of particle 2. When released, they accelerate but always remain at this same distance from each other. Find d.
