An electron is released from rest in a region of space with a nonzero electric field.

1. As the electron moves, does the electric potential energy of the system increase, decrease, or stay the same?
 
a. increase
b. decrease
c. stay the same

2. Choose the best explanation from among the following.

a. As the electron begins to move, its kinetic energy increases. The increase in kinetic energy is equal to the decrease in the electric potential energy of the system.
b. Because the electron has a negative charge its electric potential energy doesn't decrease, as one might expect, but increases instead.
c. The electron will move perpendicular to the electric field, and hence its electric potential energy will remain the same.

(a) Describe the motion of a proton after it is released from restin a uniform electric field.

*The proton accelerates in the direction of the electricfield.
*The proton accelerates in the opposite direction of the electricfield.
*The proton accelerates perpendicular to the direction of theelectric field.
*The proton remains at rest.

(b) Describe the changes (if any) in its kinetic energy.

*Its kinetic energy increases.
*Its kinetic energy decreases.
*Its kinetic energy remains the same.

(c) Describe the changes (if any) in the electric potential energyof the proton–field system.

*The electric potential energy of the system increases.
*The electric potential energy of the system decreases.
*The electric potential energy of the system remains the same.

 

For a positive charge moving in the direction of the electric field,

its potential energy increases and its electric potential decreases.

its potential energy decreases and its electric potential decreases.

its potential energy decreases and its electric potential increases.

its potential energy and its electric potential both remain constant.

its potential energy increases and its electric potential increases.
