Question

If the electric field the length of the antenna? c was constant how long would it take for the electron to a The diagram below shows the path of electrons as they are accelerated in a Cathode Ray Tube. 2. Paralel Plate A The left metal plate in Parallel Plate A is heated and emits thermal electrons. These electrons are accelerated by Parallel Plate A. The electrons are then deflected by Parallel Plate B which causes the electrons path to bend before hitting the screen. Use the diagram above and the information below to answer the following questions. Electric Field between Parallel Plates A 3500 N/C Distance between Parallel Plates A 30.0 cm On the diagram indicate the directions of the electric fields between Parallel Plates and then between Parallel Plates B. a.

Explanation / Answer

On A it will be right to left and on B top to down.

When passing through A will be accelerated in th ehorizontal directrion but while crossing the plate B it iwll experience a verticle force in the upward direction .

Acceleratoion = e E/ m = 6.15*10^14 m/s^2

With this acceleration for 30 cm the change in speed will be

V = sqrt (2 a s)

V = 19.21 *10^6 m/s
