Question

Tipler6 21.P.058. An electron with kinetic energy of 3 x 10-16 J is moving to the right along the axis of a cathode-ray tube as shown below. There is an electric field E (6 x 104 N/C) 3 in the region between the deflection plates. Everywhere else,E-o plates 12 cm How far is the electron from the axis of the tube when it reaches the end of the plates? You currently have O submissions for this question.

Answer 1

As plate chasge distnibuhion is nat providal we assume Electric field is direct~d down wand the elel ele - 25.LCx to^ m (s ris is time taken to cross 4cmざHa plalu in Ris di 25.G6 x 10' Detection electron 2 m. X (1-56x10-9 y= 12.82 x10-3 m e 2.32 mm
