Concept explainers
The magnitude of force acting on an electron.
Answer to Problem 76A
The force on each electron is
Explanation of Solution
Given:
A beam of electrons traveling with a velocity
Formula Used:
The force acting on a particle is dependent on the strength of magnetic field, velocity of motion, charge and the angle which the velocity vector makes with the magnetic field. It is mathematically expressed as,
Here, the force is to be calculated for a single electron. Hence, the charge can be written as,
Here, e denotes the charge of one electron which is
Calculation:
For the given strength of magnetic field
Conclusion:
Therefore, the force on a single electron in the beam is
