What is the magnetic force experienced by a charged particle if velocity and magnetic field are parallel to each other?

Explanation

To determine the magnetic force experienced by a charged particle when its velocity is parallel to the magnetic field, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Magnetic Force**:
The magnetic force \( F \) on a charged particle moving in a magnetic field is given by the equation:
\[
F = q(\mathbf{v} \times \mathbf{B})
