Electron, proton, `He^(+) " and " Li^(+)` are projected with the same speed perpendicular to a uniform magnetic field. Which particle will experience the maximum magnetic force?

Explanation

To determine which particle experiences the maximum magnetic force when projected with the same speed perpendicular to a uniform magnetic field, we can use the formula for magnetic force:

\[ F = q \cdot v \cdot B \cdot \sin(\theta) \]

Where:
- \( F \) is the magnetic force,
- \( q \) is the charge of the particle,
- \( v \) is the speed of the particle,
