Each of the electrons in a particle beam has a kinetic energy of 1.60 1017 J.

Question:

Each of the electrons in a particle beam has a kinetic energy of 1.60 × 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 10.0 cm?
(b) How long will it take to stop the electrons?
(c) After the electrons stop, what will they do? Explain.
