Question

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. Part A Draw a vector representing the direction of the electric field. The orientation of the vector will be graded. The location and length of the vector will not be graded. Part B Draw a vector representing the direction of the electric field. The orientation of the vector will be graded. The location and length of the vector will not be graded. Part C Draw a vector representing the direction of the electric field. The orientation of the vector will be graded. The location and length of the vector will not be graded. Part D Draw a vector representing the direction of the electric field. The orientation of the vector will be graded. The location and length of the vector will not be graded.

Explanation / Answer

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. 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
