Newer automobiles have filters that remove fine particles from ehaust gases. This is done by charging the particles and separating them with a strong electric field. Consider a positively charged particle+3.7C that enters an electric field with strength 210⁶N/C. The particle is traveling at 15m/s and has a mass of 10-⁹g.

a. What is the acceleration of the particle? ( The magnitude only. ) ( in m/s² )

b. What is the direction of the acceleration of the particle relative to the electric field?
