Maximum Frequency of Revolution in Magnetic Field – Rankers Physics

Force Acting on Moving Charges: Practice Problem & Solution

Which of the following charges has the maximum frequency of revolution in a uniform transverse magnetic field?
a proton
an alpha particle
an electron
a neutron

Solution Explained:

To solve this problem, we apply the core principles of Force Acting on Moving Charges. Understanding the underlying formula is key to arriving at the correct answer below:

Frequency of revolution in a magnetic field is given by \(f = \frac{qB}{2\pi m}\). Since the electron has the highest charge-to-mass ratio \(q/m\) among the charged particles, it has the maximum frequency.
