Electrons are accelerated in the picture tube of the television via a potential difference of 8.00 x 10^3 V. (Employ the values q = 1.60 x 10^-19 C and m = 9.019 x 10^-31 kg)
i) Determine the change in the potential energy of each electron traveling in the tube?
ii) Determine the change in the kinetic energy of electrons?
iii) Determine at what speed do the electrons strike the screen?
