The magnitude of the force on the proton, which travels at a speed of
Answer to Problem 14SP
Solution:
Explanation of Solution
Given data:
The velocity of the proton is
Themagnitude of the magnetic field acting on the proton is
Formula used:
The expression for a force acting on a charge moving in a magnetic field is written as
Here,
Explanation:
Recall the expression fora force acting on a charge moving in a magnetic field:
Since the charge is travelling parallel to the magnetic field, the angle between the velocity of the charge and the direction of the magnetic field becomes
Substitute
The charge on the proton is
Conclusion:
Hence, the magnitude of the force acting on the proton is
