2. Electrons are accelerated in the picture tube of a-television through a po- tential difference of 8.00 x 10^3 V. (Use the values q e=1.60 x 10^-19
kg and
m e = 9.109 x 10^-31 kg.)
a. What is the change in the potential energy of each electron traveling
in this tube?
b. What is the change in the kinetic energy of the electrons?
c. At what speed do the electrons hit the screen?
