5.2.2 The three types of nuclear emission (1 questions)
The relationship between the radius of curvature (r) of a charged particle in a magnetic field (B) is given by:
r = mv / (qB)
where:
- r is the radius of curvature.
- m is the mass of the particle.
- v is the speed of the particle.
- q is the charge of the particle.
- B is the strength of the magnetic field.
Velocity in this context refers to the speed of the charged particle as it moves through the magnetic field. It is a vector quantity, indicating both the speed and direction of the particle's motion.
Radius of curvature is the radius of the circular path that a charged particle follows when moving perpendicularly to a uniform magnetic field. It is a measure of how sharply the particle is deflected. A larger radius of curvature indicates a less sharp deflection, while a smaller radius of curvature indicates a more sharp deflection. The radius of curvature is directly proportional to the mass of the particle and the velocity, and inversely proportional to the charge and the magnetic field strength.
