This document discusses how an equation relating the radius of a curved path followed by a moving charged particle in a magnetic field can be applied to real-life situations. The equation shows that the radius is determined by the particle's momentum, mass, charge, and magnetic field strength. This concept applies to stringed musical instruments where vibrating strings follow curved paths, and microwave cooking where charged particles spiral inside the microwave. It also occurs inside mass spectrometers and cyclotrons which use magnetic fields to curve particle trajectories.

1. Recognize how this equation (and its underlying concepts) could be used in real-life
circumstances and situations. ( look example bellow )

mv 18
Solution
Given,
r = mv/q B = p/q B
Recognize: The above qequation is the expression for the radius of a curved path followed
by a moving charged particle in a magnetic field.
The concenpt: Basically the magnetic force is balanced by the centripital force.
q v B = m v^2/r
r = mv/q B = p/ q B
(since, momentum, P = mv)
Real life circumstance: This happens inside a mass spectrometer, cyclotron.
