A charged particle moves through a region of uniform magnetic field perpendicularly, Is the momentum of particle affected?

Explanation

To determine whether the momentum of a charged particle moving through a uniform magnetic field perpendicularly is affected, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have a charged particle (with charge \( q \) and mass \( m \)) moving with a velocity \( \vec{v} \) into a uniform magnetic field \( \vec{B} \) at a right angle (90 degrees).

2. **Magnetic Force on the Particle**:
