Force on Moving Charges & Right Hand Rule
1PRACTICE PROBLEM
A helium nucleus, composed of two protons and two neutrons, is in motion within a magnetic field B = 1.25 k T. Its velocity is measured at 2.0 × 107 m/s, as shown in the figure below. For every situation outlined, calculate the magnetic force, denoted as F, exerted on this helium nucleus. Please present your solution in terms of its components.
