Concept explainers
The angle with which the electron shall travel after it passes between the plates.
Answer to Problem 65GP
Explanation of Solution
Given:
The plates are
Formula used:
The potential energy is given by
Where,
The kinetic energy is given by
Where,
The time taken by the electron to travel the horizontal distance is
Where,
The electric field acting on the charged particle is
Where,
According to Newton’s second law,
Where,
The angle of the direction of the path of the electron is given by
Calculation:
The horizontal component of the velocity will not change as the electron passed through the plates and the potential energy is equal to the kinetic energy. Now, let
The electric field in the y direction is
The angle
Conclusion:
The angle with which the electron shall travel after it passes between the plates.
