Each of the electrons in a particle beam has a kinetic energy of 1.18 ✕ 10^−17 J.

(a) What is the magnitude of the uniform electric field (pointing in the direction of the electrons' movement) that will stop these electrons in a distance of 13.5 cm?

N/C

(b) How long will it take to stop the electrons?

ns

(c) After the electrons stop, the electric field will continue to act on them, causing the electrons to accelerate in a direction (select) at what rate?
