Each of the electrons in a particle beam has a kinetic energy of 1.10 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 7.0 cm?

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

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