Electric Field Vector Drawing

  1. 1. The problem statement, all variables and given/known data

    Each of the four parts of this problem depicts a motion diagram for a charged particle moving through a region of uniform electric field. For each part, draw a vector representing the direction of the electric field.

    2. Relevant equations



    3. The attempt at a solution

    I know that a negative charge has an electric field that that is radially inward and a positive charge has an electric field that is radially outward.

    But I'm still not sure how I'm supposed to draw it. I really hope someone here has experience with masteringphysics

  3. For the first one, the electric field points to the right because it is a positively charged particle and the acceleration is going to the right. [force and the electric field point in the same direction for a positively charged particle, and in opposite directions for a negatively charged particle.] For the second one, the electric field points to the left becuase it is a negatively charged particle and the acceleartion is going to the right. I have no idea how to do the next two...i put in a couple of tries using the concepts i developed for part A and B but apparently doesn't work quite the same way.
     
  4. miss_soup was correct for the first two and as for second two they also follow the same rules

    Part C The drawing of the vector representing the direction of the electric field goes to the right

    Part D The drawing of the vector representing the direction of the electric field goes to the left

    Conclusion : was a waste of tries thinking outside the box LMAO
