Consider the following statements about the motion of an electron placed at rest

Question

Consider the following statements about the motion of an electron placed at rest in a uniform electric field as shown: "Since the electron is negative, it will move downward at a constant velocity proportional to the strength of the electric field." "The electron will accelerate upward because particles move in the direction of the electric field, which points upward." "The electron will move downward because it Li a negative particle. The force acting tm it will be apposite the direction of the electric field. It will move with a constant acceleration." Which of these students Is correct? Anna Brooke Chico None of them Explain.

Explanation / Answer

Chico is correct

"If E is uniform (that is, constant in magnitude and direction), then the acceleration is constant. If the particle has a positive charge, then its acceleration is in the direction of the electric field. If the particle has a negative charge, then its acceleration is in the direction opposite the electric field."
