I was given this problem for homework.(adsbygoogle = window.adsbygoogle || []).push({});

Assume you have a television tube that is about 0.3 m from cathode to screen, and electrons are accelerated uniformly through 20 kV – the electric field is constant. How long does it take for the electrons to travel from the cathode to the screen? The electron mass is 9.11x10-31 kg.Assume you have a television tube that is about 0.3 m from.

Can any1 let me know what equation to start off with adn one to find the time. Thanks
