2. A proton initially moves left to right along the x-axis at aspeed of 2x103m/s. It moves into an electric field, which points inthe negative x direction, and travels a distance of 0.15m beforecoming to rest. What acceleration magnitude does the protonexperience?

(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.
