**3.** In old TVs, an electron gun accelerates electrons between two parallel plates 1.2 cm apart using a 25 kV potential difference.**a.** What is the *electric field magnitude* between the plates?**b.** If the electrons start at the negative plate at rest, with what *speed* will they hit the negative plate? (Note: this speed will be a significant fraction of the speed of light)**Diagram Explanation:**There is an image of an old television tube. It visually represents the concept of electron acceleration in the context of older television technology, where an electron gun is used to manipulate electron movement. The image may help in understanding how electrons are directed between parallel plates within such devices.
