Answer to Problem 54P
Explanation of Solution
Given:
The width of the screen is
Formula used:
The distance from the center of the screen to the bright spot on the screen is
Where,
The law of conservation of energy
Where,
The velocity of the electron is
Where,
Time taken to travel a distance of
The electric force acting on the electron along the field
As per Newton’s second law:
The acceleration,
The velocity of the deflected electron is
Where,
Calculation:
The distance from the center of the screen to the bright spot on screen where the electron hit is
The velocity of the electron is
The time taken to travel a distance of
The time taken to travel a distance of
The electric field is given by
The range is
Conclusion:
The required value is
